Gorgeous! 😍 #ctenophore

Happy #CtenophoreDay (10-04) for those in Europe, UK, Australia & others that use DD-MM-YYYY format! This bi-annual event celebrates these squishy globs of goodness 🤩 Go ahead: share your favorite #ctenophore images and videos using the hashtag #CtenophoreDay! Credit video to @oceana.bsky.social.

Happy #CtenophoreCtuesday! Enjoy this bloody-belly comb jelly (Lampocteis cruentiventer) for your moment of zen 🔊🪼 The color red is nearly invisible in deep-sea allowing these jellies to hide from potential predators. Credit video to @mbarinews.bsky.social.

Have you ever seen a #ctenophore poop? 🪼💩 While it was widely accepted that comb jellies expel waste from both ends, Mnemiopsis shattered dogma with the presence of a through-gut. Intrigued?

I've also mapped out some #scicomm I'll be starting for the #Ctenophore community called @ctenophoresrock.bsky.social w/ its first hashtag: #CtenophoreCtuesday! I'm excited to finish off some of my zfish work so the next you'll hear from me will be a preprint announcement 🤞 bsky.app/profile/cten...

Reverse development in the ctenophore Mnemiopsis leidyi | PNAS Reverse development, or the ability to rejuvenate by morphological reorganization into the preceding life cycle stage is thought to be restricted t...

Want to learn more, read about this phenomenon in this original research article published in @pnas.org (2024) by @joanjsoto.bsky.social & @pawelburkhardt.bsky.social: www.pnas.org/doi/10.1073/... #ctenophore #mnemiopsis

Life cycle and main morphological changes of the ctenophore Mnemiopsis leidyi. (A) Life cycle of the ctenophore M. leidyi. Ordinary downstream development (normal ontogenesis, clockwise) and reverse development (anticlockwise). Note the absence of tentacles in the fully transitioned lobate stage, and the presence of newly developed anatomical features (i.e., auricles and lobes) gradually appearing during metamorphosis of the cydippid stage, and shrinking until they disappear during reverse development. Illustrations of the different life stages by Nicholas Bezio.

Introducing #CtenophoreCtuesday where we'll share cool #sciart & fun facts about your favorite #Ctenophore species! This first post shows the life cycle of Mnemiopsis leidyi, which can undergo REVERSE development when fed after periods of stress 🤯 Credit illustration to @beziostudio.bsky.social. 1/2

@xenomatt.bsky.social Beautiful photo! So hard to capture the delicate shapes and iridescence. So fragile too. I have tried to draw / paint them, with little success...

Wowser! As the author of THE OCEAN'S HEART, I'm an amateur marine biology enthusiast, and this gives me 🤩🤩!!! #Ctenopalooza!!! Just l👀k at this!!! #ocean #marinebiology #ctenophore #combjellies #STEM #STEAM #scienceillustration

Calling all #ctenophore researchers and artists!
Joe Ryan is organizing the Ctenopalooza Ctwo meeting, which we will host at MBARI in California August 23-25. 🦑🧪🌊

Come swap notes with fellow enthusiasts about the latest news in comb jellies.

The Super Bowl may be over but this ctenophore (Ocyropsis crystallina) can still execute a beautiful tackle. Ocyropsis 1. Copepod 0. #ctenophore #copepod #predation #bluewater

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.

A little and large Ctenophora larvae (probably sea gooseberries, Pleurobrachia pileus) from October.

#Ctenophores! There are soooo many types! Did you know some aren’t pelagic, but rather benthic, so the live on the bottom, or, in this case, attached to this sea star?!? The tentacles aren’t stingy, so yes, they’re safe to lick. 👅

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?

Thanks to those of you brave enough to vote. :^)
Still time to sway the results with your own thoughts on #ctenophore anatomy. 🦑🧪

Today's #ctenophore day (get it, ten oh four!).
As well as the mass of Lobate comb jellies I met at Shimoda, was entranced by this Beroid; @beziostudio.bsky.social via @inaturalist.bsky.social tells me it's Flattened Helmet Comb Jelly (Beroe forskalii), complete with disco lights. #cilia #japan 5/6

Top, members of the jelly multitude I met in Shimoda - maybe Mikado Comb Jelly (Bolinopsis mikado)? or Warty Comb Jelly (Leucothea multicornis)? Below (with torch) is the Venus’ Girdle (Cestum veneris) was thrilled to meet there in Nov. No idea what the raptor foot lookalikes are?? #Ctenophore 4/6

Happy Ctenophore Day!
These glowing ocean drifters look like jellyfish but aren’t! They’re comb jellies, shimmering creatures that light up the sea with rows of beating cilia 💙🌈
Which species can you identify? 👀 Most are raised in @pawelburkhardt.bsky.social lab

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.

comb-like cilia (hairs). This multimedia piece combines my linocut comb jelly on translucent Japanese paper, and self-flashing rgb LEDs to replicate their incredible bioluminescence.
