Just a reminder that echinoderms used to have bilateral symmetry like us. Nowadays they're still born with it, but the radial adult form literally tears its way out of the bilateral larval body.

'Smothering Starfish' for the new expansion, Sunken City.

Some artists wait their entire career for that exciting 'echinoderm clinging to face' brief. Only the luckiest of us get to ride that train a second time. What a rush.

Back when I drew the inside of a REAL alien: a sea urchin.

Though ironically echinoderms are relatively close cousins of ours...

Eldonia

A misterious animal of which over 500 specimens have been found, it was suggested to be an echinoderm or jellyfish but its affinity remains unknown

ALT: one of the specimens discovered that was once believed to be a jellyfish but turned out a synonym of eldonia

Getting art from is a dream come true!
Feeling spikes erupt all over my body as I squish down into an oversized echinoderm is more like a nightmare, though. Youch!

For I am sharing one of my favorite fossils of all time: a platyceratid attached to a Mississippian (Scytalocrinus). This lived permanently attached to its host, stealing food and/or gametes. Amazing specimen!!!

Jurassic Bath Stone. Calcite cement crystals around the echinoderm fragments are clear and large (can you spot them?), and are much more resistant to weathering than small crystals around ooliths, so longest-lasting building stones tend to echinoderm-rich

Since it's shout out to Cradily - surprise, surprise, a This fossil poke "lived" in ancient shallow seas like our stalked crinoids - maybe Cradily too is still thriving in pokemon's deep oceans then.
1 flaw: 8 arms, thus failing 5-fold symmetry
