Overview

Found singly, with just the head showing, in rock lined burrows, over rubble and sandy areas of the continental shelf.
They feed mainly on benthic and planktonic invertebrates.

Jawfish are usually found in self-constructed burrows with just the head showing waiting for their prey, they have huge mouths for the size of head.
After mating the males incubate the eggs in their mouths, the eggs are clumped together like a sticky ball!
