Last week, SOSA’s Discovery team was at a workshop to study polychaetes from one of the deepest and least explored places on Earth – the Aleutian Trench! 19 individuals came together to identify and check if specimens collected from the 2022 @sgn.one AleutBio expedition were new to science!

Get some sand from underwater a shallow part of a beach (~a bucket full) and run it through a fine sieve. What you're left with is an amazing mix of crustaceans, polychaetes, all sorts of exciting invertebrates!

Chesapeake bay benthic monitoring season has started! Here’s a few highlights from our first trip on the slover(: #benthicMonitoring#LGBTQinSTEM#FieldWork#Polychaetes#TeamInvert

Capitella is one of the best-studied polychaetes, and polychaete chaetae are among the most extensively researched features of all annelids. Yet, we discovered an elusive, transient gland associated with Capitella chaetae. If you’re curious, here’s the link: t.co/mEciM6b348

To dager igjen av #InverteFest, og jeg finner dagens eksemplarer i nevøens sandkasse med den fineste kviteste skjellgrus. All grusen her var del av noe levende en gang! Det meste er rester av kalkalger, ellers er det allslags skjell og andre kalkdannende organismer. (Alt text in English.)

A hand displaying long-dead invertebrates from my nephew's sandbox. This is 95% pure carbonate sand/gravel dredged from shallow coastal waters in Vesterålen, North Norway. The bulk of the material is coralline red algae (Lithothamnion), but there's plenty of fragments of other CaCO3-shelled organisms such as tube-building polychaetes (shown at base of pinky finger) as well as smaller, whole shells of bivalve species I can't identify. Many shells have one tiny hole bored in them, which I think means that they were killed by a predatory snail drilling into the live animal?

The defence was amazing A record crowd & a slew of people online A long line of people in matching shirts, with Andrea’s face on it, unveiled A candidate that killed it. “I have a slide for that” when I asked a more esoteric question Dr Murillo Ramos even had worm earrings for her polychaetes

Dr Andrea Murillo Ramos after her successful defence. She is in the graduate pub, holding a chalice, full of smiles and toasting her success
Andrea is wearing a black shirt and is holding her long, black curly hair to show off her earrings. They are large, pink worms

New paper on the wonderful googly eyes of alciopid worms out now in CurrentBiology! We found that alongside vertebrates, arthropods, and cephalopods, this group of polychaetes is capable of high-resolution vision - but mysteries remain...🪱 👀 🧪 www.sciencedirect.com/science/arti...

Turns out hydrozoans and polychaetes have lots more CS than expected - and those fish show a deficit.
