Humphead Wrasse

• It is the largest living wrasse: there are records of 229 cm and 191 kg.
• It changes sex over the course of its life: almost all small adults are female and almost all individuals over a metre long are male.
• Its fidelity to a single spot on the reef and its lack of fear of divers make it very easy to catch, and it is among the most sought-after species in the live reef fish trade.
• It is scarce even where populations are healthy: densities rarely exceed 20 adults per hectare of reef.
