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

Nothin' to sea

>>5143920
If you want to get real mad, go look at Velella Velella and Physalia Physalis' taxonomic classifications and how velella isn't classified as a siphonophore.

Fucking god it infuriates the shit out of me.

>>5147300
My one of my professors in College used Velella as an example of a siphonophore.
Who decided that it wasn't one and why?

>>5144266
ask the starfish then.

I think these are great, don't get the hate. Tubefeet are cute.

This is like saying humans aren't actually bilateral because our internal organs are asymmetrical.

Yeah, really. They've got five of these compound eyes.
As for other echinoderms, sea urchins have photoreceptors all over their body, making their entire bodies a single giant compound eye.

>>5144266
advanced vision doesn't help you much if you can't move fast and don't specialise either

Which taxa made it to the Permian? All the Stylophorans I can find seem to have only made it to the Carboniferous.
