Some awesome broody starfish with cute baby starfish!

Starfish bearing young (brooding) is a CRAZY thing. Most species live around the Peninsular region. But there's like 5? 6? DIFFERENT lineages/groups that ALL brood in DIFFERENT WAYS. Young around mouth. Internal brooding. Brooding among arm spine baskets!

#fossilfriday More beautiful Wiltshire Middle Jurassic crinoids! Those lovely long stems are being used for an exciting research pilot study into biometrics and ecological tiering! Can you spot the starfish as well?! (Tip: look towards the bottom!)

Congratulations @NHMdinolab! As you say a very appropriate dinosaur to be named after you! Nice one @Tweetisaurus !

Some stunning crinoids from Canada. The large tongue-shaped extension in the cream coloured specimen is a huge anal pyramid! This may also be where the gonads were located (hence large size) and differs from modern crinoids where they are located on the arms.

Assorted crinoids from the Royal Ontario Museum Dawn of Life gallery this #FossilFriday. Despite being commonly called "sea lilies", crinoids are echinoderms (one of the more interesting groups I don't work on, which includes things like sea urchins).

It’s on!

@tim_ewin I am so pleased! It’s such a fantastic discovery, the marine fossil equivalent of Pompeii! Also in the Daily Mail..

#FossilFriday Another fossil from the Palaeogene Red Bluff Tuff of Chatham Island – a small, flat-topped spine from an echinoid.

The coordinated behaviour of tube feet along an Ophiuroid arm is fascinating to see. Love how the tube feet immediately go back to food capture again after they’ve passed the parcel!

アカクモヒトデ Ophiomastix mixta Lütken, 1869の摂餌行動です。管足を上手に使って餌を口の方向に移動させています。まるで運動会の大玉転がし（送り？）みたい。
