Description

The butterfish is a wrasse from the southwestern Pacific, mainly around New Zealand. The species grows to about 40 cm and has an elongate, greenish to bluish body with a beak-like mouth adapted to grazing on brown algae. It lives in shallow coastal water among rocks and kelp forests to about 20 metres depth. Like many wrasses the species is a protogynous hermaphrodite, starting as a female and later able to change into a male. It is a valued food fish. The IUCN assesses the species as Least Concern (LC).
