Distribution
editThis snail is known around the South African coast from the Cape Peninsula to Coffee Bay in depths of 8–30 m. This species is endemic to the area.[1]
Description
editTriviella ovulata has a plump, round, white to deep pink shell. In life the shell is usually completely covered with the white mantle, which is variably spotted with black.[2] It reaches a maximum size of 40 mm.
Ecology
editThis snail is usually found among colonial ascidians, on which it feeds. The snail first drills a hole in the wall of the colony, then eats its fill and finally lays its capsule-shaped egg cases in the resulting cavity. The black-spotted form of this animal resembles Mandela's nudibranch, Mandelia mirocornata, which may cause fish predators to avoid it.
