MBARI’s mechanical technicians and engineers collaborated closely to build a titanium frame capable of holding cameras, sensors, and instruments used in the SINKER—SINKing Ecology Robot—imaging system, which collects vital carbon data. 🔧 🌊 🔬 Learn more: youtu.be/6_elP8a1o0M?...

Oh, I love this. A new species of sea anemone was discovered recently that parks itself on top of a hermit crab shell like a hat. It seems to feed partly off the crab's faeces, but it also excretes a hard shell that extends the crab's home. In return, it's carried around the seafloor like a king.

30 previously unknown deep-sea species, including a carnivorous “death-ball” sponge, have been confirmed from one of the most remote parts of the planet by The Nippon Foundation–Nekton @oceancensus.bsky.social and collaborators. ecomagazine.com/news/researc... 🦑 🌊

Ummm, who was going to tell me that Phronima eat Beroe abyssicola and that when they do they and all their little babies turn pink?? Photo from today when I learned that from putting them in a kreisel together. 🦑🐙

For CTENOPHORE DAY, a little survey: Which end of this fishing Pleurobrachia is the mouth on? Please just "vote" in the comments — no definitive answers. 🦑🧪🌊 P.S. this is one of my earliest #ctenophore photos, shot on film in a home-built kreisel. P.P.S. Legit data-gathering for a future paper.

Happy Ctenophore Day! 🐙🦑🧪

Wow. Japan's JAMSTEC has a probe that goes to over 8K in depth! #deepsea japan-forward.com/japans-deep-...

Our science photo book The Radiant Sea is out Sept 2nd!! 30 years of research, 10 years of "we should", and a year of collating pix and writing. Sönke and I show (mostly for the first time) images of how organisms produce, use, and interact with light in the sea. #bioluminescence #fluorescence 🦑🧪🌊

In the deep ocean & Antarctic waters, sponges grow at a rate of fewer than 2cm/yr. While life on land seems to move at an oft dizzying pace, the size of this sponge suggests this animal may have been alive for hundreds of years. #AntarcticClimateConnections

As currently configured, NASA newest grant opportunity release represents an ****82%**** cut to planetary science research funding. research.ssl.berkeley.edu/~mikewong/bl...

BEHOLD! One of Earth's greatest lineages of life: the lil wiggle arm guys, Meteora. These single-celled critters, originally found in deep-sea sediments, are SO DIFFERENT from other lifeforms on Earth that they're likely in their own kingdom (as in, the Animal Kingdom, the Plant Kingdom etc). 🧪🌿

Death net Not much escapes from the sticky, stinging tentacles of a #siphonophore. Body of ~7”, and a net of tentacles extending >6’. Yes, this creature is on the Do Not Lick list. #forsakaliaedwardsi #nematocysts #blackwater #blackwaterdiving #chrisgug #gugunderwater #gug

Enough of you asked me about this that I wrote some brief thoughts on Ocean Ramsey's particular brand of pseudoscientific nonsense. I believe this addresses almost all of the frequently asked questions I receive, but as always I am happy to answer serious questions asked in good faith. 🧪🦑🌎🦈

It's #InternationalPolychaeteDay, and we've got something for you to celebrate. ❤️ Flame on: The vibrant red gossamer worm is the race car of the deep sea: youtu.be/PII8AvmEvnE?...

Today’s low tide finds!

So many cool nudis (and other little weirdos) at low tide this morning!

Big news! Our latest paper, “Manufacture and use of allogrooming tools by wild killer whales” has been published in “Current Biology”. This is the first known evidence of a marine mammal making tools out of objects in their environment. Explore more here: www.sciencedirect.com/science/arti...

Microscopic particles, global impact 🌊🔬 MBARI scientist @cadurkin.bsky.social and her team are using microscopic particles to reveal the mechanisms of carbon transport into the deep sea that can help improve satellite-based models of carbon export. Learn more: bit.ly/carbonexport...

I am used to photographing #ctenophores in darkfield, but under those conditions it is hard to see the pigment spots on this little (5mm) specimen. Fun to see the patterns that show up when viewed against a white background. 🧪🦑🌊

For the first time, scientists have filmed microscopic worms called nematodes in the wild as they glom together and form large wriggling masses. Learn more: scim.ag/3FBwSx3

The Presidents Budget Request for NASA is out. It’s a bloodbath Canceled are DAVINCI, VERITAS, Juno, OSIRIS-APEX, US participation in ExoMars and EnVision… Huge cut to R&A. No funding to begin development of the Uranus Orbiter. If you’ve ever cared about NASA, time to contact congress.

At the heart of MBARI’s research vessel David Packard, a team of skilled pilots commands the ROV Doc Ricketts. 🤖 Chief ROV Pilot Marko Talkovic and his team ensure every system runs safely and efficiently to support missions and advance marine science. Learn more: youtu.be/KGg_xep2vmM?...

If you happen to see a friend across the street, odds are you might raise an arm and wiggle your hand to say hello. Cuttlefish apparently do something similar—and that’s not the only arm gesture they use to communicate. Learn more: scim.ag/4j5nmQv

At MBARI, our “office” is Monterey Bay and its deep underwater canyon. Using advanced robots, we’re revealing the stunning community of life that thrives deep beneath the ocean’s surface.

A dream come true: the first expansion microscopy images of C. flexa 🤩 Generated by Mylan & Uzuki who learned from the best (@hiralshah.bsky.social @gautamdey.bsky.social @dudinlab.bsky.social). We will learn so much from these!

Some photos of Saturn are simply breathtaking.

OH WOW! A HUGE Radiolarian called Tuscaridium caught on this stalk! 4853 m #okeanos #saveNOAA Murray Fracture Zone

In the deep sea, we know all about romance. ⁠❤️⁠ ⁠ Female gossamer worms (Tomopteris spp.) produce a pheromone that attracts males and signals them to shed sperm into the water. This, in turn, signals the female to release her eggs—a behavior called swarming.

It’s hard to beat field work in Hawaii with @cadurkin.bsky.social @lenaunderwater.bsky.social and others of the @mbarinews.bsky.social team..! We are using blue-water scuba diving to study #ctenophores, siphonophores, radiolarians, and #bioluminescence. 🦑🌊🧪🤿

A couple of big diving milestones recently… completed my drysuit and AAUS scientific diver certifications!

Heading home and looking good doing it🚢⁠ ⁠ MBARI’s new vessel, the R/V David Packard, is making its homeward journey to Monterey Bay. ⁠The crew is hard at work keeping the vessel running smoothly and continuing to upgrade and outfit the ship before its arrival. Follow along: odss.mbari.org/odss/

A fun case of usual-unusual: Most luminescence in the sea is blue-green, but Tomopteris worms emit yellow light. With Warren Francis, we found a species that emits blue light — unusual but usual. 🦑🧪 link.springer.com/article/10.1007/s00227-016-3028-2 doi.org/10.1002/bio.2671

Remember how there was a pause in Hollywood productions from the strikes, etc and then TV and film kinda sucked for a while? The same thing is about to happen in science in the near future, but it's going to impact you more than a season of the The Bachelor 🧪 #NSF #NIH

How the fire affected NASA's Jet Propulsion Laboratory: About 210 employees lost their homes. Others were displaced by damage to their neighborhoods. Employees kept the institution running, some putting worst-case emergency training to use. @corinnepurtill.bsky.social www.latimes.com/california/s...
