MOAR Star on sponge action! Ceramaster munching on this glass sponge! #spongeThursday #echinoday www.inaturalist.org/observations...
oh neat! A shot of in situ feeding, Poraniopsis inflata feeding on this sponge! #echinoday #spongethursday www.inaturalist.org/observations...
Compare and Contrast! The living species, Calliderma emma from deep-sea habitats throughout the Indo-Pacific! Are they the same genus? An interesting question! Could this genus been around since the Cretaceous? #echinoday

large sea star being collected by robot arm
There were also observations of shallow species at mesophotic depths doing cool things!Here,we see the giant seastar Thromidia catalai hunched over,feeding on this sponge. These are HUGE animals. You can hold them with 2 hands! (2 separate individuals shown, similar in size) #echinoday #ashmorereef
Calliaster corona! A lovely spiny beast showing off some very impressive spination! the species name alludes to the "crown" of spines on the disk! Not only were we able to describe it-but also to see it in situ! #echinoday #ashmorereef
NEW SPECIES OF MESOPHOTIC STARS! ALERT! #echinoday
Some lovely Chiridota sea cucumbers from the Gulf of Mexico! #echinoday #okeanos youtu.be/k7bOUN5qwW0?...
A lovely video of the 50 armed sea star Labidiaster annulatus, which uses its arms and "wolf trap" features called pedicellariae to capture MOVING krill! #echinoday youtu.be/vxxbA8NkWFE?...
OH COOL! the Charleston Marine Life Center has an armored sea cucumber Psolus chitinoides with the bottom under glass! These are functionally sessile & are anchored to the substrate. Top surface covered by armor, with feeding arms into the water! #echinoday via FB www.facebook.com/UOCMLC/posts...
Whoa. Ophiura in big ATTACK on some hapless food! Toyama Bay 210 m, sped up 3X #echinoday youtube.com/shorts/Zzl-i...
Not a new species-but I described it in 2007-Akelbaster novaecaledoniae, possessed of these remarkably numerous pedicellariae on the oral surface and on the marginal plates, etc. EVERYWHERE! What are they for? I would love to find out in my lifetime! #echinoday
MORE from the MANY new starfish species of New Caledonia! There seemed to be a surprisingly large number of "cookie" or pentagonal shaped forms! #echinoday #goniasteridae MORE detail in the responses below! These were new species out of the 28 I described! www.mapress.com/mt/article/v...
Swimmy Sea Pig video !! from @nautiluslive.org #echinoday youtube.com/shorts/U42_l...
SO CUTE! Lovenia elongata, a fast burrowing heart urchin which uses its spines and tube feet! #echinoday youtube.com/shorts/zp73-...
CRAZY diversity of sea stars fr NEW CALEDONIA! I describe 28 NEW SPECIES,3 NEW GENERA! #echinoday #goniasteridae #openaccess. My thanks to colleagues at the @MNHN.fr in Paris! for my many visits in order to complete this research! Will share some of my favorites herein! mapress.com/mt/article/v...

5 people, participants of a workshop in a lab holding a sea star specimen
Calliderma emma! An amazing species collected from #CoralSeaFrontiers! this one was easily 60 cm (2 FEET) across! The STAR among the participants of the @oceancensus.bsky.social workshop on asteroids! including @drtimohara.bsky.social among others! #echinoday
Not sure these are the same species-but wow, similar!! . sometimes Hymenaster (#deepsea slime star!) just doesn't look like anything else! This one from the deeps off Australia! #echinoday
BASKET STAR! A Gorogonocephalus specimen from Australian waters! A group that DOES get around! Other species found in the Arctic/North Pacific and here in the Southern hemisphere as well! #echinoday
Ah. okay more of a basket star! Astrosierra with arm extended! Feeding! #echinoday www.inaturalist.org/observations...
oooo! Astrosierra showing off those pronounced tubercles! #echinoday www.inaturalist.org/observations...
Another Astrosierra snake star/basket star from near Sydney Australia! #echinoday www.inaturalist.org/observations...
Pic of a living Astrosierra to contrast what they look like in situ! #echinoday #australia www.inaturalist.org/observations...
