Chiroteuthis doing stuff I haven't seen them do before @schmidtocean.bsky.social dive 939 #deepwonders #MarineLife
Neolithodes 🦀? @schmidtocean.bsky.social dive 939 #deepwonders #MarineLife
Whoa, check out that Chimaera!! Not a species I've seen on a dive before. @schmidtocean.bsky.social dive 939 #deepwonders #MarineLife
Opisthoteuthis! @schmidtocean.bsky.social dive 939 #deepwonders #MarineLife
Shrimp, pycnogonid, tiny hermit crab beside zoanthid covered sponge stalk, & not sure what that coral is attached to. Urchin test maybe? @schmidtocean.bsky.social dive 939 #deepwonders #MarineLife
Apristurus! Love the dead shape on this shark @schmidtocean.bsky.social dive 939 #deepwonders #MarineLife
OMG look at this fishfall!! Big ole ray. That's a 1st for me! @schmidtocean.bsky.social dive 939 part 2 #deepwonders #MarineLife
An addition to the "Awesomely Peculiar Hall of Fame" — extremely rare sighting of a barreleye fish, & first footage of this species, Winteria telescopa, alive in situ. Filmed during the #Doldrums expedition at 710 m. Read more about tubular eyes & a light organ here: youtube.com/shorts/1bhh3...
A barreleye fish with binocular vision & a sole!

🚨Not one, but two Magnapinna squid! 🚨 the #doldrums team observed 2 elusive Magnapinna sp., commonly known as bigfin squid, at approximately 4,300 m (about 2.7 miles). Magnapinna is the deepest-dwelling squid. Sightings of these animals are extremely rare — seeing two in one dive is extra exciting!

🐙 Say hello to Inopinoteuthis magna — the big-eyed jellyhead. 🐙 And yes, that common name does makes us suspect someone’s kiddo was in the lab that day! (Special thanks to @jeffday.bsky.social for sharing this species ID when we posted a different view of the animal.) #Doldrums 2,923 m
Cirrothauma or Inopiniteuthis @schmidtocean.bsky.social dive 931 part 3 #Doldrums #MarineLife
hey if you're a scientist and you use this data in your research and you want to tell me how dumb this is, contact info is in my bio (i will also listen to scientists who think this is a great idea, if such a person exists)
they WANT us living in the dumbest timeline. i hope y'all like the dark ages
GOOD NEWS! Researchers at Stanford University have developed a UNIVERSAL vaccine known as GLA-3M-052-LS+OVA, that protects against a wide range of respiratory viruses, bacteria AND even allergens. The vaccine is delivered intranasally AND provides broad protection in the lungs for several MONTHS.
Goodbye to seasonal viruses as we know them: the first universal vaccine against respiratory infections and allergies is now closer than ever
Scientists are getting closer to a universal nasal vaccine that could protect against respiratory viruses, bacteria and even allergies

We're 60 shirts away from getting our first bug mural of the fall funded. If you haven't already, get a shrimp shirt. Look cool as hell while supporting a project that's just as cool 😎 SquidFacts.net
Welcome to Shrimp City! Teach your friends about a variety of crustaceans with this helpful visual aid - and set the record straight... bugs is shrimp. Shrimp is not bugs These shirts are designed by @the666cat.bsky.social & printed in Philly! Get one at SquidFacts.net (pls RT!)
My fish prson says this is the first Winteria in situ! I have waited 11 yrs to see a barreleye on a dive. It's my top bucket list fish. Worth every second! @schmidtocean.bsky.social dive 924 #Doldrums #MarineLife
Before that fish rendered me speechless they saw this octopus. Japetella or Bolitaena. @schmidtocean.bsky.social dive 924 #Doldrums #MarineLife
Squid squad is thinking Neoteuthis for this one @schmidtocean.bsky.social dive 924 #Doldrums #MarineLife
Ohhh I love this. Winteria telescopa, a species of barreleye - incredibly cute and simultaneously beautiful animal, paddling about in the mesopelagic without a care. (Also, good evidence for my hot take that it's a shame Macropinna is the poster child of the family 💅)
Whoa who is this fella? Some sort of barreleye? @jethroreading32.bsky.social @schmidtocean.bsky.social dive 924 #Doldrums #MarineLife
BOOSTING this again for #AAPI, Asian American Pacific Islander month! I am the first Chinese American in to be among this august if obscure assemblage of 20 #echinoderm taxonomists! and the number continues to grow!
I AM IN THE TOP 20! As of March 2026 I have described 186 species-based on data from Carter&Sands 2025 who summarize the top 20 echinoderm taxonomists (by total species) that puts me in the TOP 20! All these others are dead, white guys. I am the first who is not. #taxonomistappreciationday
🚨NEW STUDY DROP🚨 A new nearly complete specimen of the Ichthyosaur, Stenopterygius quadrissicus from the Toarcian (Lower Jurassic) Whitby Mudstone Formation at Ravenscar near Whitby, Yorkshire, England is described... 🎨: Somniosus insomnus
Does anyone who has worked with low-oxygen/anoxic seawater have any advice for setting up microcosms from Niskin bottles? What methods do you use to prevent/minimize oxygen contamination?
I was supposed to present my research on deep-sea sharks in the western Caribbean Sea at #SI2026, but I was, er... let go from my job shortly before the conference and am not there. Since I gained a few followers from this, I thought I would share some of what I would have presented yesterday (1/9)
I made a Bluesky starter pack of shark science and conservation professionals. Many are attending sharks international #SI2026 ! Please follow and share. go.bsky.app/Q1x1gJB @sharks-int.bsky.social 🧪🌎🦑🦈
