extra rare south american doggos As we know, there are rare and exotic doggos out there in the world, and as I found, all the doggos of the South American continent are all part of the same subfamily (Cerdocyonina), which are also only known from this continent (the recently extinct warrah inhabited the offshore Falklands Island though), although the group evolved and radiated in southern North America, and spread south when the Isthmus of Panama formed, later becoming extinct from North America. They are different from doggos elsewhere, but they are still good boys.  The bush dog ( Speothos venaticus), which resembles what the wild ancestor of the dachshund would probably look like. The bush dog is widespread throughout most of South America and parts of Central America (although their population is spread rather thin throughout their range). They are the most gregarious South American canid, living in packs consisting of a dominant mated pair and their subordinate kin. Their prey consists mainly of large native rodents like paca or capybara, but they are known to hunt prey as large as adult tapir. They are good swimmers, with webbed toes, often inhabiting areas near rivers, where the webbing assists in walking on the damp soil. When hunting, some members of the pack may hide in the water in case the prey being chased tries to make a swim for it. Strangely, its closest relative is the long-legged maned wolf. Bloop
Doggo and pupperino
---  The short-eared dog ( Atelocynus microtis) is a rare and elusive species found in the Amazon rainforest (and possibly up into parts of Central America). It looks similar to the bush dog, but it has a more fox-like body shape, with a long snout. It eats mainly fish and insects (it is believed it may be semi-aquatic to some degree), but has an extremely varied diet and it may be an important fruit eater. In turn they are preyed upon by larger jungle predators, such as the jaguar and boa constrictor (in both cases, a tagged dog was found to have stopped moving, and at the site was the predator instead). It is a relatively solitary animal, and reaches sexual maturity at three years of age (a rather long time for a canid). The species is very enigmatic, and very little is known about it. 
camera boi
laser-eye boi---  The crab-eating fox ( Cerdocyon thous), is as its name implies, a fox that eats crabs. However, it is somewhat misleading, as it is not closely related to true foxes of the genus Vulpes, and are instead close relatives of the South American zorro ( Lycalopex sp.), and it is not specialized to or prefer to eat crabs really any more than any other canid, only consuming them opportunistically during the wet season. Most of its diet consists mainly of small animals, like mammals, birds and reptiles, although it shifts depending on seasonal and geographical differences. It ranges throughout northern and eastern South America. The species is monogamous, although it may forage alone, although during the wet season, several pairs may forage together. The fur of the crab-eating fox is coarse and rough, and is therefore its pelt is of little value in commercial trade.

jungle demon-spiders
double scorpion beetle Onychocerus albitarsis is a species of long-horned beetle native to parts of South America which is unique in the insect world in that it is the only known species that has stingers at the end of its antennae (and since it is a long-horned beetle, it also has very long antennae that can exceed the length of the body). Onychocerus albitarsis is the only known species of beetle that is truly venomous (that is, it injects toxin, as opposed to spraying it or leaking it). It's believed that they have a completely defensive purpose, since long-horned beetles are generally herbivorous. The sting is not medically significant on humans, and only causes mild swelling.  The antennae of the beetle (second column), compared to the tail of a scorpion (first column), and the antennae of a nonvenomous Onychocerus species (third column).
forecast of the apocalypse for the next week; don't wear nice clothes I'm not actually sure exactly how "obscure" this particular species is, but I personally think it deserves a bit of recognition somewhere.  The Rocky Mountain locust ( Melanoplus spretus) is a recently extinct species of grasshopper that lived over western North America until the very early 1900s. The species was a scourge upon settlers of the 19th century, forming swarms unrivalled by any other known species of animal. One documented swarm in 1875 was estimated at over twelve trillion insects and stretched over five hundred thousand square kilometres, an area larger than the country of Spain. This wasn't even the largest reported swarm, and a swarm in 1874 was estimated at over five million square kilometres. A swarm could take days to pass over, with the skies darkened by a black cloud that stretched for hundreds of miles. Could you imagine not being able to clearly see the sun for more than a week because a group of insects was passing through? According to eyewitness accounts, the locusts consumed almost every vaguely edible thing: grass, leather, wood, the wool off sheep, the paint off walls, even the clothes off peoples' backs; people tried to protect their crops by throwing blankets over them, but the locusts would just eat the blankets. Trees sometimes became so heavy in covered locusts that their branches would snap and the ground would be smothered by a layer of grasshoppers a foot deep. Even after they left, the land would be tainted under a layer of locust droppings, which clogged the rivers and ponds, rendering the water undrinkable.  However, less than thirty years after their description, they became extinct. The cause of their extinction is still not entirely known, although it may have been accidental, as large numbers of buried eggs were destroyed by plowing. Other theories include the transformation of the land by agriculture or a lack of genetic diversity at the time. After the species extinction, North America has become the only inhabited continent without a major locust species.
deep sea fellows  The onejaw ( Monognathus sp.) is a very aptly named species of deep sea fish (living from 2000-5400m below sea level, and one of the deepest living elopomorph) related to gulper eels. Saccopharyngiformes already have very degenerative bodies, lacking ribs, pelvic fins, a swim bladder, scales, and the bones that cover the gills. The onejaw takes this even further, as it does not have an upper jaw, having no premaxilla or maxilla bones. However, they do have a pair of venomous fangs, which they probably use to capture and kill prey, although the process has not been witnessed. Just like other Saccopharyngiformes, they have a grossly distended stomach, so obviously the lack of the upper jaw does not inhibit their ability to hunt and eat. slimy fang gorlOnejaws, like many deep sea animals, are also sexually dimorphic; in males the bottom jaw too is almost absent and the fangs are not sharp. They have much better developed olfactory senses, suggesting that once mature, the males stop eating and live solely to mate and then die; because of this male specimens are extremely rare. ---  The tube-eye or thread-tail ( Stylephorus chordatus) is a species of deep sea fish possibly related to cod (although it's not thought to be closely related to any known fish). It is named after its tube-shaped eyes and elongated tail tip, which may be twice the length of the rest of the fish (about thirty centimetres). It eats mainly plankton, but it is a very unusual feeder, sucking in prey rapidly expanding its oral cavity, drawing water in, and then forcing the water out through the gills, leaving just the plankton behind.   This is how eating works, right?

1. the onejaw is yet another reason ray finned fish are better than tetrapods. Why don't we have extremely degenerate tetrapods?
2. those harvestmen are freaky. I love them,
3. the rocky mountain locust is the insect equivalent of the passenger pigeon. A once widespread and abundant pest now driven to extinction.

Don't remember if I said this, but this thread made me want to hypothesis if later tetrapod groups were able to develop some of the weird features that ray finned fish have managed. I know some of it has to do with how non-specialized fish are by comparison, so you can't just write anything willy nilly, but it could still be workable.

OK, I worry that poorly, I meant more of how those particular features I'm mulling over are a divergence from the very basic body plan our ancestors abandoned in order to survive on land.
I don't know if that wording was better...

I actually never got a clear answer. it was given during the "if arthropods can be degenerate, why can't vertabrates?" discussion, and I don't doubt it was in other discussions as well.
http://s1.zetaboards.com/Conceptual_Evolution/search/?c=1&q=degenerate&type=post&sort=desc&forum%5B%5D=236075&s_m=5&s_d=24&s_y=2008&e_m=5&e_d=26&e_y=2017
if you don't think you got a clear answer, then either a. you weren't paying attention. b. you didn't understand, but didn't ask for help. c. you understood the answer, but chose to ignore it.

You said it yourself. That was "arthropod vs vertebrates" not "tetrapod vs bony fish". The circulatory system argument applys to to all vertebrates, including bony fish. I honestly don't know what tetrapods have that prevents them from doing the stuff that fish do. The only answer that I got was metabolism, but that can't be true because most tetrapods are ectotherms.

Guys, don't fill up the rodent thread with this spam. This is a rodent-only space.
Back to Africa, like I said, great place for interesting rodents, probably because it's an island continent, but still pretty close to an now joined to Eurasia.
This time, convergent squirrels.
Now rodents are a huge group, and getting them organised nicely is not easy. But there are three broad groups, I still enjoy linnaean taxonomy, though I recognise the superiority of clades. I shall just refer to them as the Squirrelly things, the Mousy Things and the Guinea Piggies.
However, within these three, broad groups, their are smaller groups that diverse pretty early on. Mousy things is further divided into Myomorpha (mice, rats, voles, hamster, gerbils and jerboa) Castorimorpha (Beavers, kangroo rats, and gophers) and today's friends Anomaluromorpha, springhares and Anomaluridae.
Springhares, you likely have heard of. These are fairly large rodents, about three kilos in weight. Two similar species survive today, the Cape and East African springhares, and as you might have guessed they live in southern and eastern Africa.

But the Anomaluridae are more obscure. They are arboreal and closely resemble squirrels in appearance and habits. They also have tails covered in scales to help them grip on to branches.
This is the Camaroon scaly-tail. I wish I could show you a picture, but these animals have never been observed alive. They are also the only member of the group to lack a patagium. For the rest of the scaly-tails glide.

The rest of Anomaluridae is pretty diverse when it comes to body size, the Pygmy scaly-tailed flying squirrel weighs about much as a house mouse, while Pel's flying squirrel weighs as much as a rabbit.
Given they are small, nocturnal and live in trees, not much is known about them.

I honestly don't know what tetrapods have that prevents them from doing the stuff that fish do. The only answer that I got was metabolism, but that can't be true because most tetrapods are ectotherms.
I think that someone here on the forum, I do not remember who or exactly where, had given a more or less appropriate response, and this is due to the type of environment where they live, most of the more degenerate fish live in dark and deep sea environments with extreme pressure , extreme temperatures, poor food, etc. These factors may tend to cause animals to take aspects and forms quite aberrant, to the point of degenerate, fish unlike any tetrapod, they are able to live permanently there, no known tetrapod is capable of stay there permanently (Yes, whales and probably other ancient aquatic tetrapods have been able to settle there, however still need to breathe air so they can not stay underwater so long) There are terrestrial ectotherms, but they receive heat from the sun, from the surrounding environment, it is not equal to a fish at almost 1000 or 3000 meters under water where there is no sun or heat apart from some hydrothermal vents. So, this is probable the most close answer about it.
Well, back to the main point.

This special young looking cat is the Fennec fox of the felines, the Sand cat (Felis margarita) is the only cat species which lives predominantly in the deserts, having a range of distribution encompassing North Africa, the Arabian Peninsula and Middle East, is able to live on both sandy and stone terrains, Having thickly furred feet, it is well adapted to the extremes of a desert environment and tolerant of extremely hot and cold temperatures.

While writing that I was reminded I need to do a post on saltation in rodents, it's found in 4 separate lineages, from what I can remember.

@Dragonthunders: I'm pretty sure most of us have heard of sand cats, but that's just me.
