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 🦑🧪🌊

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.

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?

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. 🦑🧪🌊

It is great to see Mackenzie Gerringer's taxonomic work, describing a fish we collected from 3800 meters, featured in the @nytimes.com. We tried to spin this story to combat the blobfish's "ugliest creature" reputation, to get people excited by deep-sea exploration, not turned away. 🧪🦑

Thanks to your incredible support, THE RADIANT SEA is already the top-selling new release in... Entomology?
There are going to be some disappointed bug-huggers out there (looking at you @franzanth.bsky.social). 😉
I am hopeful they will warm up to pictures of ocean bugs like Cystisoma.

Ctenophores possess a unique aboral organ that acts as a multisensory center, controlling complex behaviors. We’ve now created a ctenophore model integrated with our 3D volume EM data. Puts it into perspective.

My favorite outcome was validating species descriptions from 18th century scientists who illustrated animals on their voyages. Their descriptions were often rejected as implausible – we found that in many cases they were exactly right. Yet another reason why @biodivlibrary.bsky.social is so valuable

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. 🧪🦑🌊
