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.
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 (土笋冻) is a delicacy in the town of Xiamen in Fujian province of China.
