The fish in the Napoleon hat

The humphead wrasse is one of the largest fish found in the coral reef. It is active during the day and at night, it sleeps in reef caves. The humphead wrasse got its name because the male sports a prominent bump on its forehead. And with a little imagination, it looks as though it is wearing a Napoleon hat.

Changes gender

Humphead wrasses reach sexual maturity around 7 years of age, when they begin to reproduce. They meet other humphead wrasses in special breeding areas. Some females become males when they are around 9 years old. We don't really know why.

Eats poisonous starfish

The humphead wrasse usually eats mussels, fish and sea urchins, but it also feeds on the poisonous crown-of-thorns starfish. Crown-of-thorns starfish populations are now so dense in the coral reefs that they are destroying them. National Aquarium Denmark, Den Blå Planet is participating in a research project focusing on crown-of-thorns starfish with the purpose of combating the destruction they cause.
