#ctenophore — Public Fediverse posts

Above is all my Raja Ampat videos starring #ctenophores but the additional species, also at Mansuar Mioskon - seemingly the #RajaAmpat #ctenophore capital! - was this angel of a Lobate #CombJelly, Spot Winged Comb Jellyfish (Ocyropsis maculata). There endeth the rabbit hole! #combjellies #Indonesia

And here also from Mansuar Mioskon is the striking Bolinopsis rubripunctata.

We also saw Leucothea Comb Jellies at Mansuar Mioskon, Raja Ampat, here against a curtain of Blue-green Chromis (Chromis viridis)

Here's more Leucothea species from Arborek, Raja Ampat - you can see the tentacles quite well.

@numenini.bsky.social "How large" was answered by Wikipedia, up to 15cm... but then, iridescence by structural colour, "photonic crystal", 🤯
Fun rabbithole! 🐇 🕳️

Also at Blackpool Sands #Devon, thrilled to see my 1st Sea Gooseberries (Pleurobrachia pileus), less so the alien #invasivespecies Sea Walnut (Mnemiopsis leidyi) introduced from West Atlantic in 1980s, likely via ship ballast in Black Sea, which competes with the Gooseberry. #ctenophore #combjelly

Five hundred million years ago, something that wasn't yet an animal became one. Nobody saw it. This week, in a lab in Jena, somebody got as close to watching it as we may ever get. 🧵 https://twp.ai/4hrZsx

1/5 A fascinating new #ctenophore preprint 🧵 Ferraioli et al. uncover a “ladder-like” neural architecture in the living comb jelly Mnemiopsis and connect it to preserved neuroanatomical traces in Cambrian fossils. But the real importance isn’t the anatomy. It’s what the anatomy implies.

@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...

A throwback for Ctenophore Day! If you ever wondered how to pronounce Ctenophore, today is October 4, the 10th month, fourth day and it sounds like ten oh four. They are a phylum of marine invertebrates, like this comb jelly which look a bit like jellyfish, but instead of stinging tentacles they have comb-like cilia (hairs). 🧵1/2

This jelly is really two in one
No, you’re not seeing double. This translucent marine creature called a #seawalnut, which is a species of #combjelly, or #ctenophore, does indeed have two mouths and two “rear” ends—pores from which it ejects waste. Yet it wasn’t born with these double features.
Injured sea walnuts can join bodies and thrive again by merging some of their systems

On the surface, this looks like #cladistic nitpicking, but in reality it is a revolution in the tree of life. Because they lack neuromuscular cells, sponges were classically presented as the sister group to all metazoans. But the sister group could well be the ctenophores, which leads to two scenarios: either several independent evolutions of neuromuscular cells, or a deletion in the sponges.
