Phyllodoce lineata against a black background. The head (top middle-left) has a bright yellow main colour, turning more muddy towards the tip. There are 4 short antennae located at the front as well as 4 pairs of long "tentacles" (tentacular cirri), 3 of which point backwards, and 1 forwards. In the front half, the back of the body, which is segmented as in all annelids, is also yellow with 3 brown spots per segment (one in the center, 2 on either side at the base of the parapodia). This gives the worm a stripy look. In the back half, the worm is entirely brown. The bottom side of the worm is a light turquoise colour and slightly iridescent. On each segment, the worm carries to leaf-shaped appendages, sometimes referred to as paddles.

It is finally #WormWednesday again! 🪱
The perfect time to post my photo of this 40 cm long beast! :D

A light pink polychaete worm with a magenta line down the center. Some parts are a bit yellowish.

I'm still weirded out by how large the proboscis in Glycera spp. is. You can see the two darker spots in the top right coil of this worm (Glycera fallax). Those are the jaws. The proboscis goes all the way to there.

Fish sleeping on serpulid worms?!? link.springer.com/article/10.1...
Very lovely photos (and very interesting symbiosis of #fish and #polychaetes) in this paper.

I now have the perfect video for the intro slide on #eDNA presentations where I say "things shed DNA as they swim around".

They were amazing! 😍 a field of sabellid #polychaetes for early #wormwednesday

An old quart-sized glass Mason jar with galvanized metal screw-on lid contains a tangled mass of preserved nereidid polychaete worms. The preserving fluid has completely evaporated leaving the worms high and almost dry. The long, segmented bodies are pale pink and contrast sharply with the dark background.

A close-up photo of the head region of a preserved nereidid showing the partly everted pair of black, sickle-shaped mandibular elements.

Rather than a #can-of-worms, how about an old mason jar? Not that I'm tempted to open it ... releasing the spirits of long-dead nereidid #polychaetes could have serious repercussions 😱. Check out those mandibles! Another treasure from an old salvaged uni bio lab collection for #WormWednesday.

A row of chaetae - hooks or "bristles" of worm in the family Maldanidae, which belong to the polychaetes. The photo was taken under the microscope. The bristles look like a bird head with a beak and a crest, and have a "beard" - some hairs that arise from under the "beak". The "head" ends in a long curved handle.

Last week I helped lead an informative workshop on mud-blister disease and how it's affecting oysters on Cape Cape cod. Meeting with farmers and growers puts my research into a translational perspective, something that I have been focusing on much more recently. #polychaetes #aquaculture #newengland

Polychaete - Wikipedia

Polychaeta is a #paraphyletic class of generally #marine #annelid worms, commonly called bristle worms or #polychaetes.

Each body segment has a pair of fleshy protrusions called #parapodia that bear many bristles, called #chaetae, which are made of #chitin.

Why worm poaching is threatening India's wetlands India's bristle worms are often overlooked. But they are crucial to the health of the country's wetlands – so local women are working to catch the poachers decimating their population.

My honors student and I are developing a mobile app to help Cape Cod oyster farmers estimate the level of Polydora worm infestation in their crops throughout the growing season based on water quality inputs. Our main issue is that we more data to train our model! #polychaetes #shellfish #diseases

Too much doom in my timeline. Send #polychaetes please.

Photo taken underwater of a colony of polychaete tube worms, probably of the genus Salmacina (they are morphologically very close to the genus Filograna, so not sure about the ID). The photo shows a dense cluster of small white tubes "hanging" from the upper half of the photo, from each tube a small reddish/orange radiolar crown protrudes (looks like a bunch of feathers). The worms use these crowns to filter particles from the water column on which they feed. They can retract into their tubes when disturbed. The photo was taken in Greece at around 15m depth.

Because it is #WormWednesday please enjoy some serpulid worms (probably Salmacina sp.). #polychaetes #greece #tubeworms
