Thyca Explained
Thyca is a genus of small sea snails, marine gastropod mollusks in the family Eulimidae.[1] These snails are ectoparasites of starfish; they are relatively unmodified, the underside having become a suction disc with a central mouth that draws nourishment from the host's tissues.[2]
Description
The conical shell is longitudinally grooved, transparent and slightly curved.[3]
