The Double Header Wrasse is a large blue-grey fish, growing to 80 cm in length, is characterised by a prominent bump on the front of its head, hence its name. Strong, pointed teeth protruding from the mouth enabling the Double Header to pry open shells, and crush crabs and sea urchins. The raw and gritty food then passes into the throat where it has a second set of 'pharangeal teeth' which grind up the hard parts, releasing the soft body tissue. The hard tissue is expelled through the mouth, and the digestible material swallowed. This fish is endemic to Lord Howe Island, and Middleton and Elizabeth Reefs.
