Polycera atra

Polycera atra feeds on bryozoans. It uses its deeply grooved radula (rows of teeth), to crush the bryozoan shell, and with a pumping action pulls out & consumes the soft tissue. Like others, in the order nudibranchia, they are simultaneous hermaphrodites, possessing both male and female reproductive organs on the side of their bodies. After they have been fertilized by another, the eggs are deposited on a surface to develop.
