Triviella millardi Wikipedia
This snail is known around the South African coast from Port Nolloth to the Cape Peninsula in 10-30 m. It is endemic to that area.
Triviella millardi has a plump round white shell, which is usually completely covered with the yellowish mantle, which is variably streaked with white or may have dark spots. It reaches a maximum size of 40 mm.
The white-streaked form of this animal resembles the scribbled nudibranch, Doriopsilla miniata, which may cause fish predators to avoid it.
