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.

While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself! Registration is free and instantaneous.

I'm positive of this. Besides, their skin is so baggy that low pressure swimming is probably more effective than via undulations.
Projects
Punga: A terraformed world with no vertebrates
Last one crawling: The last arthropod

ARTH-6810: A world without vertebrates (It's ded, but you can still read I guess)

Potential ideas-
Swamp world: A world covered in lakes, with the largest being caspian sized.
Nematozoic: After a mass extinction of ultimate proportions, a single species of nematode is the only surviving animal.
Tri-devonian: A devonian like ecosystem with holocene species on three different continents.

Actually, it's lampreys. But probably hagfish too.

Scientists have painstakingly uncovered the mechanism behind the highly efficient swimming methods of jellyfish and lampreys. Their study, published in the journal Nature Communications, finds that instead of creating pockets of high pressure to be jetted away from, these creatures actually prefer to generate areas of low pressure to be sucked into.

Then how come all footage of lampreys and hagfish swimming look like typical fish undulations?

They found that when lampreys swim, they actually create low-pressure pockets inside each bend of their undulating body, which the water ahead of them rushes to fill in. The motion of the inflowing high-pressure water “sucks” the lamprey forwards. Jellyfish, despite being physically quite different, swim using the same motion, using low-pressure pockets beneath their “umbrella” to create an identical suction effect in order to swim.

Oh, I see now. Do snakes or eels do this as well, as they have long bodies?

Maybe. I haven't done much other research into it until now. Snakes probably do something similar, given how their bodies are designed to move across the ground.

Doesn't fit exactly, but rotifers use their crown cilia to move food into their mouth like an electric toothbrush.
