Fake references are a scourge. Still waiting for the taxonomy journal Zootaxa to take action on the first case they've let slip through. Pretty easy to spot when you've supposedly written an article in the ref list and you know you haven't.

Finnish Malmgren had a brief period of interest in Polychaeta in the 1860's based on some northern expeditions. McIntosh created the genus name. It's a Finnish/Swedish family name. Dour-looking chap.. en.wikipedia.org/wiki/Anders_...

Not your average worm 🔥⁠ ⁠ Gossamer worms call the expansive waters of the ocean’s twilight zone home. Living up in the water column, thousands of feet above the seafloor, has made Tomopteris effective swimmers. They swish their bodies side to side while rowing paddle-like parapodia.

Large purple barrel sponge on a coral reef, its ruffled, porous surface forming concentric folds around a single large central opening (osculum).Tangled mass of thin, curly white fibers with fine hair-like protrusions on a dark background, shown in extreme close-up to highlight their coiled texture and delicate structure.Small white segmented marine polychaete (Cladosyllis) with numerous feathery lateral parapodia along a curved body and a rounded head, annotated with labels "an", "dc", and "pa" on a black background for anatomical identification.Close-up of a white, cup-shaped sea sponge with fibrous walls and many round pores revealing its inner chamber, attached to a dark underwater surface.

We had a chat about this worm on the Annelida email list, & agreed it's from Scalibregmatidae (not my ist pick of Dorvilleidae, & is possibly genus Axiokebuita. Would expect it to be new. Credit to @exogone1.bsky.social for the id. Most unusual to see one crawling & not in a burrow.

Geoff Read @annelidsci.bsky.social · 28/08/2026
It's a weird one. Maybe a dorvilleid. The head palps are dorvilleid-like. Hesionids have long dorsal cirri and are very agile and usually colourful. That guy lumbers along and is unpigmented. There's lots of different deep sea dorvilleids, but they're usually smaller than that. Thxs for the vid.

Worms like gummy bears swimming up to the surface to spawn. They are probably not complete polychaete worms, but instead, segments that detach and swim away from the main body just for spawning, while the actual worm stays safe and snug in its den somewhere below.

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.

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.
