Echinoderms:
Feel like a good sponge costume would allow you to pee right where you are.
I guess it depends on what kind of sponge, but I think in all likelihood since most sponges have no symmetry that this comes down to the same politics as an agender person choosing a bathroom.
Flounders are not bilaterally symmetrical.
Dafuq you say about me?
YOU’RE NOT BILATERALLY SYMMETRICAL
In the tree of life, flounders are a sub-sub-…-sub-species of bilaterally symmetrical animals: https://www.onezoom.org/life/@Holozoa=5246131?otthome=%40_ozid%3D1&highlight=path%3A%40Apionichthys_finis%3D3640785&highlight=path%3A%40Bilateria%3D117569#x2913,y-2310,w8.2796
Edit: let me preemptively be a pedant to myself and say that “sub-…-species” is wrong because “bilaterally symmetrical animals” is not a species. Flounder is itself a species AFAIK, not a sub-species of anything. It is a descendant of the common ancestor of all bilaterally symmetrical animals. There, now surely no one will find anything to be pedantic about :D
Forego the illusion of species and families. It’s taxa all the way down.
Just like starfish!
They’re “differently symmetrical.”
It depends on whether it was a larvae or not.
Pretty sure from my B- in zoo that sponges eat from what amounts to our waste hole.
So you are supposed to piss in the punchbowl and drink from the toilette.
They are a single orifice kind of animal. Take a gulp of sea water, sift oit the goodies, and expel the rest
Yeah. ok. See what kind of biological insight a B- gets you?
What if you take off the costume? Humans aren’t entirely bilaterally symmetrical (at least not on the inside) and obviously not radially symmetrical so the paradox continues.
