Unidentified myzostomids

Unidentified myzostomids
Photographed by: William Tan

Comment from Dr. Richard Willan: The flat, soft-bodied creatures living commensally with the crinoids would be myzostomids. These enigmatic animals are distant relations of bristle worms (Polychaeta), but have a soft body without any external signs of segmentation. Nothing is known about the biology of the Myzostomida, so any observations you can make on their natural history would represent completely new discoveries.

Kingdom:Animalia
Phylum:Annelida
Class:Polychaeta
Order:Myzostomida
Family:Myzostomidae
Species:Unidentified myzostomids

Comment from Leslie Harris on photo #579
The living appearance is known for only a few species and I don't recognize this particular one. Being cautious I wouldn't go below family level.
