Wow, no idea what this is.
A preprint of our latest global marine biogeography, presented at DSBS17, is available at doi.org/10.21203/rs....
Beautiful image. I will read the paper tomorrow!
Yeah, that was a cool talk.
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!
Weird looking Amphiura, the overall morphology looks more like Ophiodaphne (although I can’t see the mouthparts).
