Syllidae

Syllidae is a family of small to medium-sized polychaete worms. Syllids are distinguished from other polychaetes by the presence of a muscular region of the anterior digestive tract known as the proventricle.[2]

Schizogamy in syllid polychaete

Syllid worms range in size from 2–3 mm (0.08–0.12 in) to 14 centimetres (5.5 in). Most syllids are benthic organisms that transition to a pelagic epitoke for reproduction. They are found in all regions of the ocean, from the intertidal zone to the deep sea, and are especially abundant in shallow water.[2][3]

They are found in a range of habitats, moving actively on rock and sandy substrates, hiding in crevices and among seaweeds, and climbing on sponges, corals, hydrozoans, seagrasses and mangroves. They are generalist feeders.[4]

One species in the family, Syllis ramosa, was the first polychaete discovered to have a branching body plan.[5]

gollark: I could play osmarks internet radio™ instead.
gollark: Yes, it's mandatory.

gollark: This is NOT true. I have not in any way been sponsored by pizza companies. There have been no advertising agreements whatsoever with any companies producing pizza or otherwise to have me subliminally advertise pizza, as my profile picture is not a pizza. Since it is not a pizza, this is obviously not pizza advertisement whatsoever. No monetary exchanges or otherwise have occurred with companies engaged in pizza production for any reason relating to my profile picture. You are clearly engaged in libel and attempting to discredit my non-pizza-advertising status. It is IN NO WAY subliminal pizza advertising because I DO NOT work for pizza companies in any form. It's not pizza. There were no deals, under-the-table or otherwise, with pizza companies. No pizza companies pay for any kind of subliminal advertising involving me. People make that mistake, but I am not working for pizza companies doing subliminal advertising; that is not in any way what I am doing. I am NOT being sponsored by ANY pizza companies to display subliminal pizza advertising OF ANY KIND.
