Thanks for keeping the list updated! However, you omitted this post of mine on Caduceia/"Rubberneckia".I'm not sure if these qualify as a distinct taxon, but they're certainly odd: the cottonwood trees of Anton Valley, Panama grow with square trunks. Even their growth rings are quadrilateral:  The Atlas Obscura article mentions a study from the University of Florida on how local conditions shape the trees' odd growth, but I can't track it down. While I'm on the subject of square life-forms, the archaean Haloquadratum, found in brine pools, has square cells: Radiolaria, a clade of marine protozoa, are also known for their geometric forms of their silica skeletons:  Polyhedron-shaped radiolaria illustrated by Ernst Haeckel IT'S MINECRAFT TIME!

Of all the geckos in New Zealand, the South Island members of the genus Naultinus are widely held to be among the, if not the, most beautiful species of them all, though the Stewart Island harlequin gecko might give them a run for their money. I will present three species which may particularly catch the eye.
Spoiler: click to toggle Naultinus stellatus, or the Nelson green gecko, is found throughout the Nelson province in the northern South Island of New Zealand, as well as northern Westland, typically in forests and shrublands, often in subalpine regions. They range anywhere from 4.5 to over 8 centimeters in snout-to-vent length, and are threatened by both habitat loss and introduced predators, which includes not only introduced mammals but also introduced wasps. Another problem is poaching for the international pet trade, of which there have been several highly publicized incidents.
Spoiler: click to toggle Naultinus gemmeus, the jewelled gecko, is an endangered gecko species found in several locations of the southern South Island, including Banks Peninsula, inland Canterbury and Otago Peninsula, as well as an isolated, unmarked population on Codfish Island near Stewart Island. They reach up to 17 centimeters long, and are vulnerable to habitat loss, introduced predators and are especially poached for the pet trade in Europe. The Otago Museum has one individual alive on display that was repatriated from Germany after being illegally smuggled out of the country, and sadly cannot ever return to the wild due to possible disease risk.
Spoiler: click to toggle Naultinus rudis, the rough gecko, is endemic to the Kaikoura Ranges and reaches lengths of up to 17 centimeters long. The usual threats of habitat loss, introduced predators and poaching threaten this species as well.
All species of South Island Naultinus (as well as Naultinus in general) are found in captivity both in zoos and private collections. With NZ lizards, captive populations tend to be separated not only by species but by wild populations. For example, jewelled geckos from Banks and Otago Peninsula are not interbred as this causes them to lose all conservation value. This is sometimes as extreme (but justified nonetheless) as not breeding species individuals from different offshore islands, even if they are mostly identical.

South American opossums While many people may know of the northern-ranging Virginia opossum and others the semi-aquatic yapok of the farther south, there are in fact many species of opossum, more than a hundred in fact. However, most of these are extremely poorly known, although whether from actual elusiveness or the fact that there aren't too many people out looking for generic rat-like marsupials in the Amazon jungle I cannot comment. But without further ado, let us begin the examination of the southern american continent's numerous opossum species. ---  The lutrine opossum ( Lutreolina crassicaudata) is a weasel-like species of opposum that is almost exclusively carnivorous, and is considered the most flesh-hungry species of opossum (although it will occasionally eat fruit). They reach around a foot in length, and anywhere from 500-1000 grams in weight. An agile, all-terrain forager, the lutrine opossum is an adept runner, climber, and swimmer, preferring habitats near bodies of water and capable of diving after aquatic prey. They used to be hunted somewhat for their fur, but this stopped when it was realized the hair colour faded over time.  ---  The Chacoan pygmy opossum ( Chacodelphys formosa) is the smallest known species of opossum, reaching only about twelve centimetres in total length. It ranges only in a single province of northern Argentina. It's also something of a lazarus taxon, as there was a single specimen documented (pictured above) for more than seventy years, until 2004. This is still the only picture of the animal I could find on the internet. ---  The Patagonian opossum ( Lestodelphys halli) is one of the most southern-ranging species of marsupial, native to southern Argentina, and also one of the more bloodthirsty species of opossum. Although other opossums prefer insects and fruit, such foodstuffs are uncommon in the colder southern climate where it lives, so it has instead turned to vertebrate-flesh as its sustenance, consuming small lizards, rodents, and birds as the mainstay of its diet. It stores the fat from its feeding in its stumpy tail, which may allow it to hibernate through the winter, although this is not confirmed, as the barren and remote habitat in which it dwells results in this species being one of the least known mammal species in South America. It reaches around 20-25cm in length.  ---  The brown four-eyed opossum ( Metachirus nudicaudatus) is a species of medium-sized opossum that ranges across most of northern South America (and should not be confused with the grey four-eyed opossum, that's a completely different animal), reaching between forty and seventy centimetres in length, with about half of this made up of a long tail, and reaching around 400-500 grams in weight. It's the largest species of opossum that doesn't have a pouch (yes, not all marsupials have pouches), and instead has a lateral skin flap where the nipples are located (similar to the Virginia opossum, it has an odd number of nipples, either 5, 7, or 9). Otherwise, it's basically like a regular opossum. 
hoppers of the grass  The bladder grasshoppers (Family: Pneumoridae) are a small group of mostly nocturnal orthopterans native mostly to coastal regions of Southern Africa. Males of this group are distinguished by their enlarged abdomens, which are used for sound amplification, allowing their calls to be heard from nearly two kilometres away. They cannot create sound by rubbing their wings together and instead use their femurs to rasp the side of the abdomen. The call of the males are deep and long, while those of the females (which are generally larger than males and lack the inflated abdomens of males) are high-pitched squeaks that may be hard for humans to hear.  In several species, two male phenotypes may develop, one typical inflated type, and one uninflated type, which correlate to differing mating styles; inflated males travel far and wide in search of many females, while uninflated males stay within the same general area and have access to only a limited number of females, but tend to live more than twice as long as either inflated males, or females, since they don't have to develop such a large, energy-wasting abdomen or produce large numbers of eggs. ---  The sandgropers (Family: Cylindrachetidae) are a group of little-known burrowing insects native to Australia, New Guinea, and Argentina, which grow up to seven centimetres in length. They resemble mole crickets, but are not closely related, and can be easily distinguished by their degenerate, larviform bodies, having short, poorly-developed hindlegs, worm-like abdomens, and no wings as adults. Their long, skinny bodies are well-adapted to quickly digging through the sandy soil. It's not really known what they eat, while it was assumed they were primarily herbivorous, they are occasionally found to have insect parts in their stomach, although whether they actually hunt or just scavenge occasionally is unknown.  The telltale tunnel trails they leave in their wake. ---  The jumping sticks (Family: Proscopiidae) are a group of grasshoppers native to South America which greatly resemble stick bugs (and by extension, sticks), and aside from their ancestry from orthopterans instead of phasmids, are basically the same (elongated herbivorous insects with extreme mimicry native to the tropics), if you want to keep them as pets, their care is similar. Not really much else to say about them really, just thought they were neat, especially since everyone's already heard about orthopterans that resemble leaves.   Sometimes they're also known as horse head grasshoppers. Neigh.
vegetarian louses  The booklice/barklice (Order: Psocoptera) are a group of small, generalized insects that feed mostly on detritus and plant matter, but also have a taste for starchy household items like book bindings, stored grains, and wallpaper glue. They rarely exceed a few millimetres and are considered the most primitive group of paraneopterans (which includes thrips and true bugs), because they still retain mandibles and have not evolved a proboscis or piercing stylets; only a small rod-like structure on part of the maxilla, which is used to scrape fungus and algae off of bark for consumption. They vary widely in appearance, even within individuals of a single species, where specific populations may have or not have wings, breed sexually or asexually, have three ocelli or no ocelli. Some male barklice have a structure known as Pearman's organ located on their hindlegs, which are used to produced sounds to attract females similar to some orthopterans, although many species are parthenogenetic; some other species communicate by tapping their abdomen on the ground. The group as a whole has a widespread cosmopolitan distribution and is good at dispersing far and wide, often being among the first insects to reach newly formed islands and colonize new habitats. Some species are gregarious and form silken colonies along the branches of trees. A few species live in the nests of birds, where they feed on shed feathers, fallen detritus, and skin flakes; although they do not harm the birds themselves, it has been speculated that this may have been where parasitic lice evolved (psocopterans are close relatives to phthirapterans, the blood-sucking type of lice). 
marine leeches  Although the vast majority of species are freshwater animals, there are about a hundred species of leeches found in the ocean, which parasitize fish, crustaceans, and other sea creatures. They are poorly studied, but other than the fact they prefer seawater to pond water, most do not appear to be that different from the typical bloodsucking leech.      One particular genus of marine leeches are the turtle leeches ( Ozobranchus spp.), which (as their name implies) only seem to target turtles (although a single specimen was found on a dolphin once), attaching to sensitive regions such as the neck, mouth, and cloaca. Very little is known about them, because it's already hard enough to study sea turtles at sea, let alone their parasites; we don't know if the leeches are capable of surviving without their host for any amount of time, or the specifics of their life cycle. At least one species seems to complete its entire life cycle on its host, a very unusual trait among leeches, as it will cement its eggs directly on the host, which immediately begin feeding on the animal when they hatch. Occasionally, heavy infestations of turtle leeches can be fatal, as the discomfort will cause the turtles to stop eating, and leeches will fill every possible orifice, preventing them from seeing, smelling or hearing. The leeches will eat the turtles to the bone, and can also carry a dangerous virus that causes severe tumor-like growths on turtles.   
prehistoric millipedes  The archipolypods were a superorder of extinct early millipedes that lived from the Silurian to the end of the Carboniferous (although fossil trackways suggest that millipedes may have existed since at least the Ordovician) of Europe and North America. They didn't reach spectacular sizes like the more famous Carboniferous Arthropleura (the largest reached about thirty centimetres in length), but they were important because they are the earliest known land animals (seems like the armoured vermiform design was real popular during the Early Paleozoic), that is, they were fully terrestrial and not semi-aquatic. They had large compound eyes and also seemed to have pretty spiky and weird shapes to them.  Cross-section of a segment.  
deep sea sharks (and one non-deep sea shark)  The bramble shark ( Echinorhinus brucus) is a rare species of squaliform shark that normally dwells near the seafloor, at depths of 400-900 metres in seas worldwide. It has brownish-coloured skin and reaches up to three metres in length (with females being larger than males), but is mostly distinguished by the large thorny denticles that cover its body. On some parts of the body, closely packed denticles will form small spiky plates, and this is what distinguishes the species from the closely related prickly shark ( Echinorhinus cookei), which has a uniform coat of spines. A sluggish predator of smaller sharks, fish, and crabs, this species is rarely encountered by people. The species is ovoviviparous and the female may give birth to anywhere from fifteen to fifty pups. Its skin is covered in a foul-smelling slime and it was reported that one captured female emitted a green glow when it was caught.  I really could not find any good pictures of living bramble sharks on the internet. ---  The crocodile shark ( Pseudocarcharias kamoharai) is a species of lamniform shark and the only member of the family Pseudocarchariidae, and is native mostly to tropical waters worldwide (although a single specimen once washed up on the shores of England). At around a metre in length, it's the smallest living species of mackerel shark (members of which include great whites and megamouths), although its relations among the group are not clear; its small size and long body and enormous liver (up to a fifth of its weight may be liver) make it convergently similar to mesopelagic dogfish. A nocturnal hunter, the crocodile shark has very large eyes for detecting prey in dim light, and a relatively small number of long pointed teeth for snagging small squid and fish. This species is also ovoviviparous and produces four pups per litter (two per uterus); unlike some mackerel shark species, the fetuses do not try and eat each other inside the womb, although why some species do and this species does not is unknown. The species is occasionally caught as bycatch, but the most notable incident of interaction between crocodile sharks and humans was when a deep-sea optic cable was lain down between the Canary Islands, but crocodile sharks were biting holes in the cable as it was being put down, presumably attracted by the electrical signals it gave off.  ---  The viper shark ( Trigonognathus kabeyai) is a very rare species of lantern shark dogfish known from parts of the Pacific Ocean and differentiated from other dogfish species by its long protruding teeth and triangular jaws, which give the species its name and allow it to grasp prey. It grows up to half a metre in length, but can swallow prey up to forty-percent of its body length. Uniquely among dogfish, the viper shark is able to expand and push out its jaws, which gives it an impressive gape to envelop large prey items. The eyes and most of the body (particularly the underside) are covered in photophores.   A real gobbling shark. ---  The bigeye sand tiger ( Odontaspis noronhai) is a rare species of lamniform sand shark that is closely related to the better known sand tiger shark ( Carcharias taurus), and the smalltooth sand tiger ( Odontaspis ferox), but can be distinguished by its large reflective eyes and dark brown skin. It is very poorly known, and the specimen pictured above is seemingly the only known photographed individual of a living animal. The species reaches up to twelve feet in length and it's assumed its behaviour is similar to other sand tigers and other deep sea fish, but otherwise little is known about the species; it is suspected the species ranges widely in tropical waters based on its sightings.  ---  The lollipop catshark ( Cephalurus cephalus) is a species of catshark (although a more recent study suggests it may not be a catshark but part of a more distantly related family) known from off the coast of the western United States around California, and is readily identified by its disproportional body, including a grossly enlarged head and gill region and long slender body, resulting in a tadpole-like shape. The reason for this is hypothesized to be that the region which it lives is oxygen-poor, and as an adaptation it has evolved expanded gills to make use of the poor oxygen content in the water. The body is soft and jelly-like, and adults don't reach more than a foot in length. I couldn't find any better pictures than this. ---  The winghead shark ( Eusphyra blochii) is a species of hammerhead shark native to the waters around Southeast Asia and Australia, which reaches between four and six feet in length. It is the basalmost species of hammerhead (which suggests the first hammerhead sharks had huge cephalofoils which became smaller over time), and is most notable for its enormous cephalofoil, which may be half the length of the body. Despite its ungainly shape, this outrageous adaptation has numerous benefits; the winghead has the greatest degree of binocular vision among hammerheads (and presumably most, if not all, sharks), and the longest nostrils (each nostril is more than twice as wide as the mouth), which gives the shark both excellent depth perception and sense of smell. The distance between the nostrils also makes it easier to determine which direction a particular scent originated from. The longer cephalofoils also provide a much larger surface for electroreceptors, allowing the shark to more easily detect the bio-electric fields of prey animals. 
L O N G G scale bois  The file snakes ( Acrochordus spp.) are a group of aquatic snakes native to Southeast Asia and Australia which are notable for their saggy skin which has scales that are roughly pointed in shape. This is an adaptation to grip the slippery bodies of fish and amphibians; the extra surface area and sharp scales minimize the chance they can escape once captured. They also lack the large, flat belly scales of regular snakes because they are entirely aquatic and so don't really need them for slithering around. They can reach over eight feet in length, with females being larger and wider than males. In at least one species, the hunting style differs between sexes, with females being sedentary ambush predators and males being active foragers As constrictor snakes, they are not dangerous to humans.   ---  The spider-tailed horned viper ( Pseudocerastes urarachnoides) is a species of viper native to Iran that has evolved a specialized tail end that resembles an arachnid such as a camel spider or spider. While hunting, the snake simply sits still and wriggles its tail back and forth slowly and soon enough the prey will come running, or more accurately, flying. The species seems to be specialized entirely to prey on insectivorous birds (more specifically, it seems to prey on migratory birds, as native birds have evolved to recognize the difference between real spiders and fake ones), which are lured with the promise of easy prey and are instead grabbed and eaten by the camouflaged snake (it's possible that small reptiles and mammals may also be lured, but this is not known). This trait was so unusual that when the species was first seen in 1968, it was thought that the tail end may have been an abnormal growth caused by a disease or parasite. It wasn't until a second specimen was found in 2001 with an identical tail that it was seen that this was not a tumor or unique mutation, but a normal trait of an undescribed species. However, the trait does not appear until the snake reaches adulthood (young snakes seem to have a more generalized diet) and since it will inevitably get pecked at, may suffer damage over time.  ---  The Iwasaki's snail-eater ( Pareas iwasakii) is a species of snake native to the Yaeyama Islands (southwest of Japan), which as its name suggests, is a specialist snail-eater. But not only that, it is specialized to eat snails that coil clockwise, with asymmetrical jaws to accommodate this; it has several more teeth on average on its right lower jaw than on its left jaw. This seems to have resulted in great evolutionary pressure for snails that coexist with it to evolve counter-clockwise shells, which it has a much more difficult time gripping, which is similar to cases with snails and snail-eating snakes worldwide, as regions where snail-eating snakes live have a much greater percentage of counter-clockwise coiling snails than other parts of the world (twelve percent compared to five percent).  ---  The crab-eating water snake ( Fordonia leucobalia) is a species of coastal water snake native to Southeast Asia and Northern Australia, which as its name implies, is specialized to feed on crabs (and other crustaceans such as shrimp and mud lobsters). However, as crustaceans are unwieldy prey, the snake has several unusual adaptations as a result of its diet. It is one of the only snake species that will dismember its prey before swallowing it, ripping off the tails of mud lobsters and pulling off the legs of crabs, sometimes not even bothering to eat the body. Also unusually, it has evolved particularly robust teeth and strong jaw muscles in order to pierce and crush the shell to envenom and more easily pull apart its prey. It's also suspected that the snake may crudely chew up crab legs before swallowing them to more easily digest the hard-shelled food items. Additionally a salt gland rids the snake's body of excess sea water within the consumed crabs. The species coexists with another crab-eating snake species ( Gerarda prevostiana), which is closely related and also dismembers its prey before eating, but the fact both consume crabs seems to have been an independently evolved trait; this species is not quite as specialized to cancrivory and seems to prefer soft-shelled crabs as a result.  Ironically, one of the main predators of young crab-eating water snakes are large crabs (maybe they're trying to snuff them out before they become a threat?).
flab fish  The flabby whalefish (Family: Cetomimidae) are a group of primitive deep sea acanthopterygii fish native to the Southern Hemisphere that are so unusual, for a very long time, the juveniles and males were both believed to be completely separate families of fish ("Mirapinnidae" and "Megalomycteridae", respectively), until it was discovered recently that they were all the same animals. As with many deep sea animals, their anatomy has become extremely bizarre to suit their life in the darkness. Most generically, their eyes are more or less vestigial, their bodies are soft, and their stomachs and mouths can stretch to accommodate very large prey. They are named for their loose, scaleless skin, which in females also has a very well-developed lateral line, which they use to navigate through the abyss. The faces of whalefish are often brightly coloured (although unlike many deep sea animals, they don't glow), but this is a neutral feature, as no colours are distinguishable to deep sea animals at such a depth. Whalefish display extreme sexual dimorphism, with females most closely resembling regular fish; they have huge mouths and expandable stomachs to swallow huge food items. The juveniles, which are known as tapetails, have small mouths and feed mainly on tiny copepods closer to the surface (that is, slightly less than a kilometre deep as opposed to three or four kilometres deep). Adult males have their mouths fused shut, their esophagus and stomach degenerate, and they become unable to eat. They instead develop a massive liver that metabolizes the shells of the copepods they consumed when they were larvae, which becomes their energy supply for the rest of their lives.  
animal Bowengriphus perphlegis is a species of aquatic animal that lived in the Late Permian of Australia and seemed to reach about fifteen centimetres in length. The two known fossils of it "displays a double-looped feeding apparatus bearing small conical elements". And that's basically the extent of which we know about it. That it was an animal probably. The illustration above is extremely speculative and relies on the assumption that Bowengriphus is a relative of the Cambrian taxon Odontogriphus omalus, an idea which was proposed in the original description of Bowengriphus based on a few supposed anatomical similarities, but now appears to be dubious as more recent studies of Odontogriphus involving more complete specimens which suggest it was a stem-mollusc, which leaves Bowengriphus perphlegis as an incertae sedis within the kingdom Animalia. Although there are several other fossils that are also incertae sedis within kingdom Animalia, Bowengriphus is unusual because of its age; animals with fur had already appeared on land, and in less than twenty million years dinosaurs would appear, but we still have no idea what Bowengriphus was.

Wow you stole so many of mine... that i was definitely, for sure going to get around to posting.
Anyway, for anyone who's interested here's a recording of the extremely loud sound produced by male Bullacris: https://sixlegsphoto.files.wordpress.com/2012/07/bullacris_r.mp3
Possibly my favorite sound produced by any animal, it's just so eerie.

Quotes "Arthropod respiratory systems aren't really "inefficient", they're just better suited to their body size. It would be quite inefficient for a tiny creature that can easily get all the oxygen it needs through passive diffusion to have a respiratory system that wastes energy on muscles that pump air into sacs. (Hence why lungless salamanders, uniquely miniscule and hyperabundant tetrapods, have ditched their lungs in favor of breathing with their skin and buccal mucous membranes.) But large, active insects already use muscles to pump air in and out of their spiracles, and I don't see why their tracheae couldn't develop pseudo- lungs if other conditions pressured them to grow larger."-HangingTheif
"Considering the lifespans of modern non- insect arthropods (decade-old old millipedes, 50 year old tarantulas, 100+ year old lobsters) I wouldn't be surprised if Arthropleura had a lifespan exceeding that of a large testudine"-HangingTheif
"Humans have a tribal mindset and it's not alien for tribes to war on each other. I mean, look at the atrocities chimpanzee tribes do to each other. Most of people's groupings and big conflicts in history are directly or obliquely manifestations of this tribal mindset."-Sceynyos-yis
"He's the leader of the bunch You know his Coconut Gun is finally back to fire in spurts. His Coconut Gun Can make you smile If he shoots ya it's firing in spurts. His Coconut Gun Is bigger, faster, stronger too! He's the gun member of the Coconut Crew! HUH!

A reconstruction of an Emuary (Emuarius sp.), a ratite from the late Oligocene and early Miocene of Australia. Like its name suggests (which is a mix of emu and cassowary if you didn't notice), they have both emu- and cassowary-like features. There are two known species

Ocepechelon is an extinct genus of giant dermochelyoid sea turtle known from Late Cretaceous (late Maastrichtian stage, 67 Myr) phosphatic deposits of the Oulad Abdoun Basin, Khouribga Province of Morocco. It is known from the holotype OCP DEK/GE 516, a complete but isolated 70-cm-long skull, making it one of the largest marine turtles ever described. It was first named by Nathalie Bardet, Nour-Eddine Jalil, France de Lapparent de Broin, Damien Germain, Olivier Lambert and Mbarek Amaghzaz in 2013 and the type species is Ocepechelon bouyai. The feeding apparatus of Ocepechelon, a bony pipette-like snout, is unique among tetrapods and shares unique convergences with both syngnathid fishes (unique long tubular bony snout ending in a rounded and forward directed mouth) and beaked whales (large size and elongated edentulous jaws).

Monitor lizards are pretty neat, but they are mostly just different sizes and colours right?
Spoiler: click to toggle Well, not this guy the Earless monitor lizard, Lanthanotus borneensis. Technically speaking it's not a true monitor lizard, but it is a close relative of Varanidae.
Spoiler: click to toggle The Earless monitor lizard is in fact they only member of the family Lanthanotidae. Quite where Lanthanotidae fits within the lizards has been debated for quite some time, originally they were thought to be close to the gila monster and beaded lizard.
Spoiler: click to toggle But it now seems likely they are close to Varanids. Interesting thing is that while I might refer to them as close relatives, these groups emerged during the cretaceous, they have been evolving along separate lines for tens of millions of years.
Spoiler: click to toggle They are quiet little inhabitants of Boreno, preferring to live in wet environments with their ideal habitat being rocky jungle streams. They can even swallow food while underwater, not something many other lizards can do.
Spoiler: click to toggle Naturally such a pretty animal is popular in captivity, however, breeding success is limited and very recent. Most animals on the market are wild-caught. Given their secretive lifestyle it's hard to know how well they are doing, but it looks concerning.

I thought not. It’s not a story the newbies would tell you. It’s a forum legend. Lyvatan was an admin of the forum, so powerful and so wise he could use science to influence the human imagination to create life… He had such a knowledge of the forum that he could even keep the ones he cared about from leaving.Speculative Evolution is a pathway to many abilities some consider to be unnatural. He became so powerful… the only thing he was afraid of was losing his admin power, which eventually, of course, he did. Unfortunately, he taught his apprentice everything he knew, then his apprentice banned him while he was offline. Ironic. He could save others from leaving the community, but not himself.

The Hawaiian islands used to be home to a bewildering variety of ground-dwelling birds, ranging from the turkey-sized moa-nalos to bizarre land-dwelling ibises and kiwi-like ducks. But today, only one of those landlubbers survives, and the fact that it still exists at all is a miracle. The Laysan duck is a smaller relative of the mallard, found exclusively on the northwestern Hawaiian island of Laysan. It displays a number of adaptations one would expect from a bird living on a tiny island--it is smaller than its relatives, its wings are relatively short and its flight muscles are reduced. Unusually for a duck, it feeds almost exclusively on flying insects, which it catches by running after them on the ground. It rarely flies, and never for long distances. The Laysan duck was once reduced to a population of no more than seven individuals when introduced rats and rabbits turned the island into a barren dust bowl. Three other birds from the same place--the Laysan rail, the Laysan honeycreeper, and the Laysan millerbird-- were killed off, but the duck managed to survive and has become the subject of a successful breeding program. Today there are more than 500 of the ducks, although the population was dealt a severe setback after a tsunami in 2011. Nevertheless they are recovering nicely and the species may even be down listed from Endangered to Threatened by next year. Populations have also been established on Midway Island and Kure, as "insurance" against any future threats to the main population on Laysan. It would be remiss of me to end this without noting that the Laysan duck is an animal with some interesting spec potential. As a land-dwelling duck seemingly in the process of evolving away from flight and towards running, it could open up an entire new niche for ducks. . . if only there weren't so many pesky humans in the way.
Predatory flightless ducks. You heard it here first.
