>actually echinoderms aren't radially symmetrical because of this off-center piss hole
Bullshit-ass animal, get your spiny ass OUT of Bilateria
>>
>>5143920
asymmetry is a feature, not a bug
>>
Why did they evolve like this?
>>
Never understood why none of these evolved proper eyes. I imagine they'd become something similar to proto mollusks
>>
>>5144266
They wasted their evolutionary history evolving into sessile forms and are currently too occupied with backtracking from it. It's honestly fucked up that they need to ditch a perfectly good bilateral larval form for some cnidaria wannabe bullshit as seen in >>5143924.
>>
>>5144270
The ones who kept that larval form went on to become other branches of life and crowd out the niche for anyone trying to get into the game late.

>>5143920
tell me, do you have a liver on each side?
a spleen?
an apendix?
gall bladder, duodenum, pancreas, stomach, aorta?

you fucking pretend symmetrical worm
>>
>>5143924
they yearn to be internal organs

>RETURN TO BILATERIA
if you want a large swarthy man to rotate your guts 90 degrees on the axial plane
>>
>>5144388
I rotated your mom's guts 90 degrees on the axial plane, if you catch my drift
>>
to think this could have been humans. all that clusterfuck biology and bizarre physiological gymnastics, just to have even less brainpower than a fucking ant. thse things suck. At least sponges and cnidarians have simplicity as their shtick and arnt trying to be complicated

Seriously, had a perfectly workable bilaterian slug thing going on and then they pull this bullshit

Like seriously, come the fuck on, this shit lasted until the end-permian? 200 million years of this? This is the type of shit that's supposed to show up like twice in the burgess shale and never be heard from again
