A black-banded sea krait underwater

Black-banded sea krait

Black-banded sea kraits are highly venomous snakes that live and hunt in reefs using their bite to paralyse prey. Newly-hatched kraits eat sand smelts and sand perches, but as they grow they switch to other prey, such as surgeonfish and damselfish. They are slower swimmers than their prey, so tend to ambush fish amongst the coral rather than hunt them in a chase.
