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.

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.

Where did you get that from? Ray fins are as specialized for an aquatic environment as tetrapods are for a terrestrial one.

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.

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.

no, that was one set of examples from 5 seconds on this site's Search function. your question was repeatedly answered, and it has nothing to do with this thread's subject.

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.Posted Image


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.
Posted Image

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.
Posted Image

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 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.

Anomalures are particularly useful in that they have styliform bones, and are possibly the longest lived gliding mammal lineage.
