Wow! #wormwednesday

#WormWednesday Minoru Imajima illustrated with great clarity. This is Lepidonotus akunanae from 2011. Not all polychaetes lend themselves to such artistic featuring. www.marinespecies.org/polychaeta/a...

🐛 Genetic and morphological analyses have been used to clarify the true boundaries of the scale worm genus Eunoe, revealing that only six of the twenty-one species previously assigned to it truly belong there. 🔍 Read more: doi.org/10.3897/zookeys.1283.168195

Divers and coral spawn are not the only things looking to have a romantic evening on the night of the full moon... Fireworms coming to surface to spawn.

Nephtyidae for Nephtys. (it should have been spelled Nephthys after the goddess, but someone stuffed up). Horrid spelling to get right.

Happy International Polychaete Day! These plankton grow up into the whole ridiculous range: sea mice, bloodworms, giant tube worms. Epic phylum!

oh neat! A lovely Nereiphylla so many paddles! #wormwednesday www.inaturalist.org/observations...

The other day a colleague complained that too much of @inaturalist.bsky.social was naturalists competing to take glamorous nature photos. Uh.. WHY IS THAT A PROBLEM?? 😂 #wormwednesday scaleworm www.inaturalist.org/observations...

Finally, footage from that new whale graveyard. The fact that fossils and fresh carcasses mix together in this spot is bonkers. But of course it makes sense, because the scavengers that live down there also need a steady supply over millions of years. They can't just suddenly adapt to the deep.

This is the 1st time I've seen a Flota swimming with the little stick legs fanned out. Usually they're moving fast and have them pulled in like little spikes @schmidtocean.bsky.social dive 929 #Doldrums #MarineLife

One of the largest and prettiest #scaleworm I’ve ever found. There’s a term, “meroplankton” which describes organisms who will spend only part of their lives, or earlier life stages drifting by with the plankton. #blackwater #blackwaterdiving #polychaete #deepseacreatures

If you look at the @inaturalist.bsky.social world map of distribution Helobdella leeches are everywhere - except the too cold near-polar places. They are also good invaders - as obviously has occurred here. But behind the hype an interesting find nevertheless.

[New Paper] in Ecology @esajournals.bsky.social reports a remarkable limpet feeding exclusively on chitinous tubes of deep-sea tubeworms! Chitin may be key energy reserves in the deep. New species in the family Osteopeltidae previously only known from whale fall. OPEN ACCESS: doi.org/10.1002/ecy....

Malaysian Myzostoma livin' its best life! hangin with its feather star host! #wormwednesday #myzostomida www.inaturalist.org/observations...

Myzostoma! interesting texture on this one! #wormwednesday #myzostomida www.inaturalist.org/observations...

Very happy to have the final chapter of my PhD published, describing the first abyssal species of Myzostomid annelids! This new genus was found living ectocommensally on abyssal seastars across the Pacific Ocean doi.org/10.1071/IS25...

Crikey! And it's been sitting on YouTube for 13 years without a comment. Amazing! Myzostomids are very strange worms.

ha ha. late #WORMWEDNESDAY Swimming Scale Worm! from EX1706! I remember being there! youtu.be/Bi_3JQULCwM?...

Wonderful zooms on a large Tomopteris! A little less than a meter probably. @schmidtocean.bsky.social dive 903 #DesigningtheFuture3 #MarineLife

GLOW WORMS IN LONG BEACH HOLY SHIT!!!

What do you get when you study deep sea annelids & sea sponges on the Getsuyo Seamount? A symbiotic relationship resulting in two newly-described species of Hesionid from two sister-clades! Inhabiting the same sponge host, they share a niche...suggesting convergent specialisation! 🧪

Impressive macrotubercles arrays

oh Wow! A male epitoke (reproductive stage) of this polychaete, Proceraea hanssoni! #wormwednesday www.inaturalist.org/observations...

Star-shaped worm colonies? ✨🪱 Our new paper describes 𝘚𝘢𝘭𝘮𝘢𝘤𝘪𝘯𝘢 𝘴𝘵𝘦𝘭𝘭𝘢𝘦𝘣𝘢𝘺𝘦𝘯𝘴𝘪𝘴, named after Mauritania’s Baie de l’Étoile (Bay of Stars). Open access & featured on the Feb cover of Ecology & Evolution. 🔗 doi.org/10.1002/ece3... #newspecies #polychaete #taxonomy @sgn.one @oceanspecies.bsky.social

The balloon worm looks nothing like a typical worm because it doesn’t live on the seafloor, it floats in the deep midwater. With a gelatinous, bag-like body for buoyancy, it drifts and feeds on sinking organic particles. www.youtube.com/watch?v=N5KG... #marinelife #wormwednesday

I am done screaming into the void today so here you go, have a whole loaf of scale worm. That thing is huge. From @schmidtocean.bsky.social dive 784 #antarcticclimateconnections #MarineLife

Kwajalein has a lot of these! NOTOPYGOS! #wormwednesday and thanks to Scott Johnson for these great shots! www.inaturalist.org/observations...

New paper out on the impact from a deep sea mining test in the Pacific Ocean. Great collaboration with the Natural History Museum London and the National Oceanography Centre Southampton . www.nature.com/articles/s41...

#Crustmas and #wormwednesday!

One day we might learn what the "tubeworms" were that formed this convenient refuge for fish. They are identified only as a Lamellibrachia.

📢 The First Circular for the 15th International Polychaete Conference (IPC15) is out! Join us in Frankfurt, Germany • 27–31 July 2026 #IPC15 #Polychaetes #Annelida polychaete-association.com/ipc15-frankf...

Palola worms! is for EATIN'! #wormwednesday Indonesia www.inaturalist.org/observations...

Meet Spinther bohnorum n. sp. Tilic & Rouse 2025 ✨— a tiny but stunning worm! Spinther species are enigmatic worms that always seem to dwell on sponges, but we still don’t know exactly where they belong on the annelid tree of life. A shiny small mystery wrapped in glitter, basically. 😅🪱

Whoa indeed! What life form is that? #WormWednesday

SO MANY PATTERN! from India! Hesione ceylonica! #wormwednesday www.inaturalist.org/observations...

Usually, when something or someone touches a Christmas tree worm's feathery radioles, it would immediately retract back into its hole. But not blennies and gobies - the worms consider those fishes as homies who are allowed to touch their radioles. #Invertebrate 🧪 link.springer.com/article/10.1...

Porcelain crabs are the icon of "fooled ya, not crab". But Eulenaios cometes goes further by living inside a worm tube! (Actually, several true and false crabs, and a second worm, are all up in these tubes wtf) 🦀🧪🦑 #InverteFest peerj.com/articles/2930/

Sad news that Dr Janet (Bradford) Grieve passed away on Saturday. She was a world expert in Copepods, a pioneering woman in biological oceanography in NZ and first women to lead a marine research voyage in nz with her first voyage in 1967. She was a role model, a mentor and a leader.

Wow. Scale worm? OP reads "Plankton fr the coast of Hitachinaka City, Ibaraki Prefecture. Body length 0.7mm. Perhaps a polychaete larva? It has a distinctive transparent disc-like structure, .. Its eyes are cute too." via @a1AgqW93RTKPUD9 #wormwednesday
