New paper in Nature: global evolutionary biogeography of my favourite animals. www.nature.com/articles/s41... theconversation.com/five-arms-no... www.theguardian.com/environment/...

A preprint of our latest global marine biogeography, presented at DSBS17, is available at doi.org/10.21203/rs....

It’s out! A new faunal inventory for deep sea habitats around cold seeps off Costa Rica, including sone cool brittle-stars, see zookeys.pensoft.net/article/1343...

Here is the long lost brittle star Asteroschema monobactrum, last collected over a hundred years ago, from the SE seamounts of Chile. Merry Christmas!! #oceancensus #museumsvictoria

I have found old friends on seamounts in the SE Pacific, same species as from seamounts off New Zealand & Australia. Never ceases to amaze me how far these animals have dispersed across open oceans. #taxonomyworkshop2024-ID #chile

Woohoo, the Cocos (Keeling) Island seamount makes the front cover of DSBII. Mapped for the first time by the RV Investigator in 2022. Now I had better finish the macroecology paper …

The @oceancensus.bsky.social #taxonomyWorkshop2024 in Chile CONTINUES! Here, drtimohara.bsky.social, world ophiuroid expert from #museumvictoria studies ASTEROSCHEMA one of the most widespread #deepea serpent stars! #echinoday How many new? species will we find?? #falkor

Also a quick note to those who are following.. THIS is Dr. Tim O'Hara's proper Blue Sky account @drtimohara.bsky.social‬ · the other one is some other guy with the same name!

Today’s marine biogeography thought: the first brittle stars to reach remote oceanic islands are Amphipholis squamata & Ophiactis savignyi, both polyploids! Super-dispersers!
