| Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

It doesn't say that the green is due to copper, it says that the green is caused by an excess of the chemical that causes bile to be green. I know that's the one you mentioned but it still doesn't say that copper is involved in the OP. |

He was talking about the milk frog, which appears to have blue colored blood. (I have no idea if it has anything to do with copper, however. I find it unlikely that a vertebrate would completely switch from iron based blood to copper based blood. The lizard still uses iron.) |

I was talking about the milk frogs, hence why I quoted the milk frog section and not the skink one. I have no idea if they have copper-based blood, I just wrote it as a possible suggestion for the colour. |

No, it's found in individuals of all ages. Younger frogs are whiter on the outside and their toe pads aren't as blue, but their mouths and groin areas are the same bright blue color. The frog with its mouth open is a juvenile. If it's just warning/shock coloration, I can't imagine why they would have blue intestines... |

Ateleopodiformes, sometimes called jellynoses or tadpole fish, are teleosts with a skeleton made almost entirely of cartilage. They're not small- some are more than two metres long- and they're found in temperate and tropical oceans in the mesopelagic zone, where they eat benthic invertebrates. Their common name comes from the fact that they are stuffed full of gelatinous connective tissue- perhaps related to the fact that they also lack a swim bladder, and require adaptations to decrease their density so they can better control their buoyancy. Their thin, translucent skin enables you to see just how much jelly is in that snout and it almost looks like they're a fish that's been eaten by a jelly snake. They're not closely related to the barreleye, another deep-sea teleost with lots of jelly in its face. ![]() (NOAA) ![]() A surprised-looking fresh specimen (taken from Kaga et al, 2015) They remain very mysterious creatures, and though they're somewhere close to the Lampriformes their exact taxonomy is frustratingly vague, and further study could give us some really interesting insight into the early radiation of neoteleostei. But for now we just have to content ourselves with the fact that they exist and they look really goofy. Here's a video of the one in the top image doing its thing. |

The flowering vine Marcgravia evenia is native to Cuba and has some pretty odd-looking inflorescences.![]() (Corinna U Koch) Those egg-shaped reddened structures in the middle are the flowers, and those odd-shaped protruberances below them are bracteoles, which in many plants serve a sort of protective function for the flowers. But here, they have become highly modified, becoming extrafloral nectaries full of energy-dense nectar, accessed from the top like a pitcher plant. An organism like a hummingbird putting its head into one of these to feed would brush up against the flowers above and become dusted with pollen. It's not an abundant plant, so it needs pollinators that range widely to transfer pollen from individual to individual. So far so good, but what's up with those two concave leaves above the flowers? They're definitely not in the optimal shape and configuration to be collecting light, so they must be doing something very important. In 2011, researchers looking at the acoustic properties of this leaf shape discovered that it produces distinctive, strong and multi-directional echoes, perfect for making it clear and recognisable for Monophyllus redmani, a highly mobile species of nectarivorous bat with a wide home range that feeds on its nectar. Just like other flowers use strong visual signals to draw the attention and recognition of bird and insect pollinators, this plant has developed an analogous acoustic signal.

The Musophagidae are an obscure African family of birds most closely related to bustards. Several groups of species within this family go by different names, with turacos, plantain-eaters and go-away birds being the most common. Oftentimes literally running through the treetops, these birds will eat fruit, leaves, flowers, and small animals. They have a particular taste for bananas (hence the name), pawpaws, and grapes, and even wild birds can be tame enough to accept hand offers. Their biggest claim to fame, however, is the fact that only species within this family use the only known truly green pigment among any birds -with other birds using a combination of yellow pigment and blue light refraction-, as well as using a unique red pigment in place of the normal carotenoids. The eponymous pigments turacoverdin and turacin are what contribute to these birds dazzling variety of colors, as shown below. Left: Great Blue Turaco, Corythaeola cristata The largest extent species of turaco. Right: Guinea Turaco, Tauraco persa Below: Ross's Turaco, Musophaga rossae Edited by Ivan_The_Inedible, Dec 30 2016, 06:48 PM.

I love turacos so much! They always have them in zoos and aviary places, which is probably where I first encountered them. Never knew that they're related to bustards though sonthat's interesting. |

Aldrovanda vesiculosa is a species of rootless, free-floating eudicot freshwater plant in the family Droceraceae, the same family as the Venus Flytrap and sundews. It bears quite a widespread geographic distribution, being known from populations in Europe, Asia, Africa, and Australia, but in recent years has become rare enough to be classified as Endangered by the IUCN; it has become reduced to only fifty confirmed extant populations and while displaying high degrees of morphoplasticity across its range, global genetic diversity is extremely low. As to be expected from its phylogenetic placement, it, too, is carnivorous, making it and the aforementioned bladderworts the only known carnivorous freshwater plants, but what makes Aldrovanda vesiculosa (known informally as the waterwheel plant or simply waterwheel, due to its arrangement of floral rosettes) truly special is that its traps utilize the very same design as the Venus flytrap; its sharing of this otherwise unique mechanism, combined with some genetic analyses, have led to the belief that it and Dionaea muscipula are sister taxa to one another, with the sundews representing a more primitive branch of the Droceraceae.![]() This picture quite clearly depicts the structure and arrangement of A. vesiculosa's trap-bearing floral rosettes - the root behind plant's common name, "waterwheel".. While currently undergoing a significant loss of range, A. vesiculosa is still the most widely-distributed species of carnivorous plant in the world. This is due to the fact that its main method of spreading to new locations is through seeds stuck to the feet of waterfowl, leading to a distribution across global waterfowl migratory routes. To speak further of the species' reproductive patterns, flowering in the species is a delicate affair, with small white blooms held above the water line by their peduncles opening only for a few hours prior to retreating below the water, where seeds form. Due to this extremely strict arrangement, flowering is not terribly successful in most circumstances, and as such does not constitute the species' main method of reproduction; instead, it primarily reproduces via vegetative growth, which occurs quite rapidly due to the species' rapid growth rate. Plants are not cold-tolerant, however, and rely upon the production of starchy, nutrient-filled turions to survive the winter in cold areas; while individual turions rarely survive, they are produced in enough quantity to typically ensure a healthy renewal the following spring. ![]() A large grouping of waterwheel plants showcasing the species' capacity for vegetative duplication.

We have a Discord server! If you would like to join, simply message myself, Flisch, or Icthyander. Some of my ideas (nothing real yet, but soon): Refugium: A last chance for collapsing ecosystems and their inhabitants. Pansauria: A terraforming project featuring the evolution of exactly one animal - the marine iguana. Mars Renewed: An insight into the life of Mars thirty million years after its terraforming by humankind. Microcosm: An exceedingly small environment. Alcyon: A planet colonized by species remodeled into new niches by genetic engineering. Oddballs: Aberrant representatives of various biological groups compete and coexist. ..and probably some other stuff at some point (perhaps a no K-T project). Stay tuned! | |
