Kind of sad I didn't get better pics, as this species isn't well-represented on the net. Upper left is Serpulorbis and lower right is a sabellid worm.
Saw more peanut worms than I think I ever have before.
Not sure what kind. About 5 cm long in the recoiled state shown here. Never really got it to relax and extend itself.
I was thoroughly convinced this was a sea cucumber, until I was completely failing to find anything like it in Light's, decided to flip through the worms, and saw it under the Sipunculans. I mean, spiny skin! Feeding tentacles! Still so much to learn.
Does anyone know if these things are known to brood? If you look you'll see a smaller one with yellow tentacles to the lower left of the big one.
The Sipuncula or Sipunculida, sipunculid worms or peanut worms, are a phylum containing 144-320 species (estimates vary) of bilaterally symmetrical, unsegmented marine worms. Sipunculid worm jelly (Ã¥Å“Å¸Ã§Â¬â€¹Ã¥â€ Â») is a delicacy in the town of Xiamen in Fujian province of China.
