- Related to high pressure, @ibudin.bsky.social and Jacob Winnikoff led a study which showed that a particular lipid headgroup (PPE) is more abundant in membranes of deep #ctenophores. 🧪🦑 What was amazing was when they put PPE into bacterial membranes, the bacteria became more pressure tolerant!
- The re-analysis of this #sponge #ctenophore study made me realize how important it is to really *look* at your data. Their filtering pipeline was meant to retain "strong" genes, but many of them had NO ctenophores and most had polyphyletic sponges. Time to put down the pitchforks for a while.
- Our eLetter github.com/caseywdunn/s... responding to a recent Science paper was just posted. The paper found more genes with consistent support for sponge-sister than ctenophore-sister. We found several technical issues that, when corrected, reverse the conclusions and recover ctenophore-sister.
- This is a limited, regionally relevant post, but… I’ll be giving a talk at the Sanctuary Exploration Center in Santa Cruz on Friday Jan 16th. Come say hi if you’re in town. 🦑🧪 (I’m presenting in San Francisco in early Feb as well)

- A survey for Ctenophore Ctuesday: * What way is this comb jelly swimming? Up or Down? 🧪🦑🤷♂️🌊🤿
- OK, this is wild! Smithsonian Magazine included The Radiant Sea in their Best Photography Books of 2025! 😲 From the start, our goal was to entice people with pretty pictures, and then sneak in the science, so to have both appreciated is a complete thrill. 🦑🧪📸 Not bad for a couple biologists :^)
- Not to mention… we just had our 4th ever sighting of Haliphron in over 35 years (7000+ ROV dives). Its arms were closed up but we followed it until we could see that it was again holding a jellyfish… m.youtube.com/watch?v=4_lt... See also: www.nature.com/articles/sre...
- Our book The Radiant Sea was chosen as one of five "Must Buy" science books by the Wall Street Journal! :^D I don't like to promote Am@z0n, but... it is on sale there for super cheap right now too. Image below showing fluorescence of one of the animals featured in the book. 🦑🧪🌊

- Reposted by Steve Haddock“Cellular Olympics” our catalog of freeky ultra fast cellular superhero’s is freely available “Ann Rev of microbiology” www.annualreviews.org/content/jour... This is a compilation of world’s fastest single cell organisms - enjoy this buffet of rare delightful protists with mind bending speeds. 🧪
- Let's do another #ctenophore survey. You are scuba divining and see this lobate comb jelly cruising in search of prey. Is it swimming to the LEFT or RIGHT? 🦑🧪🌊
- Apologies that I'm going to be all about THE RADIANT SEA for the foreseeable future, but .... 😉 Our book has been released in the U.K. now and should be available at your local bookshops! 🦑🧪 (with @sonkejo.bsky.social)
- Thanks to those of you brave enough to vote. :^) Still time to sway the results with your own thoughts on #ctenophore anatomy. 🦑🧪
- 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.

- Not to hijack this thread, but our book The Radiant Sea includes 35 pages of fluorescent animals (and humans.. and asparagus). Here is a young strawberry squid showing green fluorescence in the eyes and red fluorescent caps on its photophores. 🦑🧪🌊
- @sonkejo.bsky.social and I were interviewed by @mdlaplante.bsky.social for his UnDisciplined podcast www.upr.org/podcasts/103... I don’t like hearing myself speak so I haven’t listened back, but my mom “LOVED IT”, so that counts for something. 😉 Support public radio, Utah PR, and @npr.org 🦑🧪🌊
- 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 🦑🧪🌊
