Happy #CtenophoreCtuesday! For your moment of zen, enjoy this floating rainbow 🔊🌈🪼 Every Tuesday throughout June, we will be featuring 🏳️🌈-colored images/videos of our favorite comb jellies! #PrideMonth #ctenophore 🦑

What is the evolutionary origin of the organizer? New work from @kremnyovs.bsky.social, @tclebedeva.bsky.social & Hejnol Lab @uni-jena.de reports the blastopore lip of the #ctenophore Mnemiopsis leidyi, a member of the evolutionary sister group to all other metazoans, exhibits organizer activity.
"Wound healing responses (which involve the reaggregation
of cells and maturation into a tissue) in diverse animals (e.g. #sponges, #cnidarians, and #ctenophores) share transcriptional similarities with M. vibrans aggregation."
Very cool findings (and #scicomm!) from Gerdt & Ruiz-Trillo Groups 😎
Happy #CtenophoreCtuesday! For your moment of zen, enjoy this calming video of a Leucothea pulchra swimming through the water 🔊🪼🌊 This comb jelly has rows of beating cilia (ctenes) that refract light, giving the appearance of 🌈-colored pulses. #ctenophore #PrideMonth 🏳️🌈 🦑

Experiments using the comb jelly Mnemiopsis leidyi and the sea anemone Nematostella vectensis reveal that the emergence of a core signalling pathway may have been a key innovation enabling the transit...
Embryonic ‘organizer cells’ can tell embryos of various phyla what kind of body to build.

We have a sea gooseberry bloom here in Norfolk at the moment! Thousands of gooseberry-sized comb jellies (ctenophore) are currently washed up on our beaches, glistening in the sun. And yes, they’re plankton!

For decades, cellular aggregation was considered an evolutionary dead end.
Cells could come together temporarily.
But complex multicellular organisms like animals?
Our study, led by JP Gerdt, with Ruibao & @jennahed.bsky.social suggests it may be time to rethink that🧵 #ProtistsOnSKy
