Wheres Wally?...

The Maori Wrasse is also known as the Humpheaded or Napoleon Wrasse. It is one of the largest reef fishes in the world and is the largest member of the Wrasse Family Labridae.

The mature adults have thick lips and a prominent hump on their forehead. Juveniles can be identified by their pale greenish colour and two black lines running behind their eye. 

Maori Wrasse are extremely long-lived, known to live for 30 years and taking 5-7 years to reach sexual maturity.  Adult females are able to change sex, when a dominant male dies. 

Adults are solitary roaming the reef during the day and returning to caves and ledges to rest at night.  Pairs spawn together as part of a larger mating group. The planktonic eggs are released into the water and once the larvae have hatched they will settle out on the substrate. 

Using their tough teeth, the Maori Wrasse is able to consume hard shelled species such as molluscs, echinoderms and crustaceans.

This species is very friendly and a great attraction for all visitors to the Great Barrier Reef.
