It's believed that this bright blue color has strong antioxidant properties typical of echinoderm carotenoids, but it may also be an aposematic warning.
Blue stars produce 'asterosaponins' which aren't harmful to humans but taste bad & make the star's tissues hard to swallow.

Always a pleasure to have @chiahsinhsu.bsky.social visit the @nhm-london.bsky.social Fossil Echinoderm collections! For his PhD Chia-Hsin is studying evolutionary change in #Cretaceous echinoids from the chalk, some of which (like Hagenowia) exhibit 'extreme' morphologies.

Surprise Pelagic Holothuroid, EX2304 Dive 4 from NOAA Okeanos image archives. ~2000m off Aleutians. Approx 5 threadlike tentacles sparsely branched, a larval condition.
Sorry, no scale.

In October 18, 2006, an unsuspecting sea snail would take a bite out of fast food and end up having a bizarre dream involving everyone's favorite porifera, echinoderm, and copepod.
Happy 20th anniversary, CftKK!

Absolutely unacceptable behavior of museums not fulfilling their mission. And not just in vert paleo! I've unfortunately encountered situations in echinoderm paleo where access to certain type specimens was similarly restricted. The story about that dinosaur holotype being sold is next level awful

Who knew sea urchins were this organized? How’d they find our flyer? Where’d they get a printer? And all those tube feet yet not ONE could hit spell check?

I'm worried people will think this is just a fluke of photography.
Like, here's a photo of Hippasteria muscipula from Okeanos Explorer off the coast of Hawaii in 2015.
This echinoderm has back.
Pixar has expressed interest.
It works the glutes.
