Another stunning brittle star with striking color patterns! Ophiothela tigris from the Indian Ocean! www.inaturalist.org/observations...

‼️ Mystery Jelly Incoming ‼️ This itty bitty jelly (~2mm) showed up at my nightlight in the Salish Sea last night and it doesn’t match anything in my local reference book or iNat occurrences for this area. www.inaturalist.org/observations... Have some thoughts, but would love more 🐙🪼🦑

The cave brittle star Amphicutis stygobita is a small microphagous deposit-feeding brittle star that survived and grew in captivity by consuming detritus rich in microorganisms and a sticky biofilm containing extracellular polymeric substances. More about this species at doi.org/10.3897/subt...

A brittle star likely in the genus Ophioplinthaca, from Blake Spur Trough, seen during #Okeanos EX2107 #echinoday

on my mind recently ASTROPHIURA! This curious brittle star that RESEMBLES a sea star! They live in the #deepsea and have been seen by #Okeanos as well as #Falkor. its POSSIBLE I may have seen something like thus during the #chile #invertebratetaxonomyworkshop2024! such nifty critters!

A deepsea brittle star called Stegophiura ponderosa! but whose disk looks very much like a UFO or underwater base! This is the reward for ophiuroids.. looking at these smallish critters reveals amazing patterns and structures! #echinoday

Brittle Star at the Point Loma tide poils

The six rayed Ophionotus hexactis from Antarctica! I always find 6 rayed brittle stars to be a delight! #echinoday

A shallow water tropical Indo-Pacific brittle star called Ophiolepis superba! Distinctive patterns on the disk-but are they just variation? separate species? MYSTERIES! #echinoday

A wonderful beast I identified as Ophiothrix foeveolata! It has DOTS! #echinoday

The reveal #InvertAdvent The Snake Star Ophiopsammus maculata. This is the largest known brittle star. It is a predatory species which ambushes prey, even very mobile species like squat lobsters. Probably not humans, but you never know.

This one is not so common here - probably only the second time in 15 years I’ve found this in the UAE. Goniobranchus alius is the name #🦑 #🦐 #Nudibranch

Each year more content moves into the #publicdoman and hence @biodivlibrary.bsky.social can make more articles freely available. Today I've added articles from the Annales of @socentomolfr.bsky.social 1923-1928 to BioStor biostor.org/issn/0037-9271 and these will appear in BHL shortly.

I get that the news cycle is packed right now, but I just heard from a colleague at the Smithsonian that this is fully a GIANT SQUID BEING EATEN BY A SPERM WHALE and it’s possibly the first ever confirmed video according to a friend at NOAA 10 YEAR OLD ME IS LOSING HER MIND (a thread 🧵)

Seems like it's getting to be that time in the semester: I am sorry, but I am not available for you to interview me for a homework assignment. I am probably available to zoom with your whole class and answer everyone's questions at once.

For #TrilobiteTuesday, here’s the aptly named Kayserops megaspina, a Devonian trilobite. First printed in castable resin, then cast in sterling silver and oxidized to yield blue highlights. Sculpted from scratch, no scans. #paleoart #sciart

A just smashingly wonderful shot of my colleague Dr. Allen Collins @agcollins.bsky.social on #Okeanos a few years ago.. little red jelly for scale! taken by talented photographer Caitlin Bailey of GFOE!

@PoPville WHOA. As of 8:30 this big ass tree had fallen from the storm blocking entrance to Georgetown Hospital on Reservoir at 38th. All buses D94 blocked in both directions. Probably for awhile

No. No they should not. And California has had it with unaccountable, anonymous federal officers.

Is haptonema still considered a poorly studied organelle?

Ilyoplax tansuiensis peforming asymmetric waving, found in Korea. Walking times during waving seemed to be shorter than what I saw in Taiwan. 韓国で見たタンスイチゴガニです。この日観察したウェービングは台湾で見たものより横歩き時間が短い気がします。 🦀🦑🧪 #crab #カニ #invertebrate

These are related to kelp & diatoms & all 3 have fucoxanthin, a pigment unique to the harosan kingdom! Do you know if the tubes are separate or continuous with the scales?
