Congratulations to the team! Echinoderms rock!

Based on our findings, we report that the sea urchin juvenile body plan is head-like, similar to what has previously been demonstrated in sea stars and brittle stars, suggesting that echinoderms in general are predominantly head-like organisms.

Yes, it can be October and puffy white clouds. @fridayharbor.bsky.social
Thank you @nswa.bsky.social for our field trip to Friday Harbor labs. #invertebrates #echinoderms #eyes

Also, not to brag or anything, but I’m certified in ID’ing mollusks, echinoderms, and sponges. www.fathomverse.game/about

Day 27 of #Paleoctober2025

🐬 Hemisintrachelus (~25 Ma)
A whale-dolphin from the Late Oligocene.

🌀 Cyrtograptus grayianus (~440 Ma)
A marine worm-like organism related to echinoderms. It was discovered by Elizabeth Gray, a pioneering woman in paleontology.

day 27 of #paleoctober2025 is cyrtograptus, marine organisms related to modern day echinoderms such as starfish and sea urchins 🪸

mRNA splicing variants of the transcription factor Blimp1 differentially regulate germline genes in echinoderms

There used to be a guy who did weekly trivia in this one social media group...he eventually blocked me after I pointed out that "group of organisms with a network of channels for moving water around" (lightly paraphrased) could describe sponges, echinoderms, or vascular plants.

Crinoids, aka sea lilies, look like lilies in this plate from Kunstformen der Natur (1904) by Haeckel, but they are in reality echinoderms, animals with five-pointed radial symmetry seen in the stem ossicle cross sections that look like stars.
Coin for scale.

Absolutely jaw dropping, spectacularly preserved & beautiful fossil crinoid (left) and blastozoan (right) echinoderms. These fossils are from the Bromide Fm of Oklahoma and nearly all specimens shown here are from the type collection at the Sam Noble Oklahoma Museum of Natural History 🧪

We love a menagerie!

William Saville-Kent’s “The Great Barrier Reef of Australia” is a trove of photographs & vibrant lithographs. Tumbling all these echinoderms together creates a kaleidoscopic effect that reflects the biodiversity present on the reef!

for 'star fish' they aren't fish they're echinoderms

This rare starfish grew into a square shape instead of the usual star. The unusual form comes from a developmental defect that changed its body plan during early growth. Starfish are echinoderms, a group that normally shows radial symmetry with bodies arranged around a central axis.

Spent some time in my prep room tonight and cleaned up some echinoderms from the Mississippian Burlington Limestone.

This one isn't quite done, but there was a hidden second blastoid. It was a nice surprise.

i need to draw more+this is kinda outdated but here's my jotaro selfship thing. the "story":he wouldnt give me a chance ever unless+until we actually bonded over smth which would likely be actually caring abt invertebrates esp echinoderms and not jsut charismatic mammals. typical selfship from there

Another post for #SciArtSeptember day 27:
A crinoid depicted by scientific artist Sarah Hall in my copy of Palæontology of New-York by her husband James Hall, published in 1847. Note the perfect little pentagons in the aboral cup; five-pointed radial symmetry is a characteristic of Echinoderms.
