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.

On multipoda there are 3 continents that are isolated. On these continents life could not be more different.
There are 3 phyla of land animals, the tripods, quintapods, and hexapods. What kind of life could exist on Multipoda?

The creatures have a carbon composition, the star is a K star slightly smaller than Sol, multipoda is covered in water and there are no ice caps.

Multipoda:
Size: 90% Earth radius.
Gravity: 95% Earth gravity.
Atmospheric composition: Methane, oxygen, carbon dioxide, hydrogen, argon, nitrous oxide (laughing gas), nitrogen, water vapor, and ammonia.
Atmospheric composition by percent: 30% Nitrous oxide, 15% oxygen, 15% nitrogen, 20% chlorine, 5% chlorine dioxide, 5% nitrogen dioxide, 5% carbon dioxide, 2.5% xenon, and 2.5% water vapor.
Atmospheric pressure: 130% Earth.
Distance from star: 1 AU.
Temperature: 6 degrees hotter than Earth. Keeps hot because of the nitrous oxide (over 200 times as effective as carbon dioxide) and carbon dioxide.
Star: Orange dwarf star 0.8 solar radius and 0.6 solar luminosity.

Because of the the high amount of xenon (make up 2.5% of the atmosphere) spectacular lightning storms exist on Multipoda.

The creatures mainly breathe nitrous oxide (N2O) and ammonia (NH3) (but they can use any mixture of nitrous oxide, ammonia, oxygen, nitrogen, and hydrogen) to use the oxygen and hydrogen they breathe and combine it with the carbon they eat to form glucose and the nitrogen they use for the electron transport system (because the 2nd shell has only 5 electrons in it, it can take 3 electrons in the electron transport system instead of the 2 as in oxygen, so that 2 transports of nitrogen forms 3 glucose, while oxygen would form 2 glucose, making nitrogen more effective) (knowing biology rocks).

They breathe through holes on the top of their bodies, have 4 eyes (1 pair seeing in infrared, the other pair seeing in visible light) and reproduce by holes usually at the base of the tail or neck that can close with a hard covering so that they're protected.

Who likes the idea?

Are you plausible?

I thought the whole point of the project was several different limb setups. Don't split it out! Say it ain't so!

Fine! But I don't want the flyer to be a hexapod.

That's totally your call.

What about one taxon with a bauplan made of repeating segments, where it's easy to add or lose a segment and so change the number of legs?
My speculative dinosaur project. With lots of fluff, parental care and mammalian-level intelligence, and the odd sophont.
