Common coloration of this species is cream with brownish-purple blotches. The animal hunts and eats fish, and is often observed at crevices and caves, preying on sleeping fish. It is venomous and can sting humans.
Habitat: sand bottom, around shallow reefs. Distribution: Indo-Pacific.
This was a live one, which I spotted towards the last leg of a night dive at Dayang Beach. It was in shallow water, very close to shore (about 3m depth). I tried waiting for it to emerge from its shell, but I was already low on air and the surge was making me dizzy. You can see part of the mollusk's mantle in the 2nd photo.
