Info

Thyca crystallina looks like a mussel, but this species is a parasitic snail of the blue starfish Linckia laevigata.

Thyca crystallina lives on the blue sea star and sucks the hemolymph and the tissue.This snail not only feeds on the starfish tissue, it is also the cause of secondary bacterial infections(wounds).
