Glittering Deepworm

Evolved from the pirouetting deepworm in the ocean depths. The glittering deepworm has moved away from becoming a true filter-feeder and instead actively hunts for magnum carpotesta luceremundare and marephasmatis using a primitive 'eye' (basically just a sunken pit with light sensing cells at the bottom allowing a certain amount of directional vision). Light-emitting bacteria have taken to living in special compartments where the vestigial remains of the carapace overlap the body of the worm which attracts prey and can also be used as a signaling device between deepworms. This is important because they possesses a rudimentary system for sex. There are no sexes, two worms simply shed reproductive material into the water near each other and hope for the best.
