is a genus of sea snails, marine gastropod molluscs in
the family Nassariidae. Most Nassarius species are very active scavengers, feeding
on the flesh of dead fish, etc. They often burrow into marine substrates and
then wait with only their siphon protruding, until they smell nearby food.
diet consists of detritus, leftover/uneaten food, decaying fish and other
organics, as well as fish waste.
