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.

A spherical comb jelly floating against a dark background, with its tentacles deployed, tentilla (side branches) fanned out. There is a number 1 above the body and number 2 below the body. Photo by S. Haddock taken around 1990.

I'm lamenting that bluesky doesn't have a native Poll option, and the third-party solutions that I found don't support images. How are we supposed to implement Ctenophore Am I Hot or Not?

Thanks. That is much warmer than I was envisioning for Bergen!

What is the water temperature there now? Mnemiopsis has such a wide tolerance for both temperature and salinity!

Thanks @dannastaaf.bsky.social !
The cephalopods definitely make featured appearances in all 5 sections. 🦑

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. 😉

OOPS: 3260 meters, but still pretty deep.

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. 🧪🦑

My first sighting of The Radiant Sea in the wild, at our local bookshop. If you have any “encounters” I would love to see them. 🙃 #booksky

Picture of several piles of books including The Radiant Sea, looking shiny.

HI Alex. Was that exhibition for The Deep by @clairenouvian.bsky.social ? If so, I saw it in Paris (would be fun to visit Reunion though!)
Our book does have echoes of The Deep, but no plans for an exhibit at the moment. That exhibit came from Claire's absolute dedication and unmatched energy.

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.

Thanks Allen! :^) You should see a lot of familiar friends in there and hopefully some new friends too.

Steve Haddock @stevehaddock.bsky.social · Aug 28

:^) I know, but ... didn't want to promote a certain mega-site and it is pretty easy to find it.
I'm hoping that local bookstores will have it on the shelves after Sept 2 in the US, early October in the UK, and early November in Europe.
I will post discount codes if the publisher lets us.

BTW I updated the Bioluminescence and Biooptics starter pack with a couple new faces. Let me know if you should be included..! go.bsky.app/9wFuWB9

P.S. Sönke is laying low on bluesky, so I neglected to tag @sonkejo.bsky.social in the original post.

I hope to take a PhD student in 2026 to study siphonophores. Please reach out if you are interested in applying this fall. For examples of recent lab projects see www.sciencedirect.com/science/arti... and academic.oup.com/gbe/article/...

Hi. It looks like it will come out in the Netherlands on Nov 8th but you can preorder online. In the UK I think in early October. Thanks for the interest :^)

Steve Haddock @stevehaddock.bsky.social · Aug 28

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 🦑🧪🌊

It seems like a bad sign that WaPo used a European hurricane prediction in their article instead of a NOAA forecast.
US science is doomed. ⛈️

That is fun that he’s your brother. Have you ever been in print together in the same issue?

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.
