Western Blue Devil
This brilliant deep blue fish is easily recognised by the iridescent blue spots densely covering the body and reaches a maximum size of 36 cm. Found from the Houtman Abrolhos, WA, to Port Phillip Bay, Vic the Western Blue Devil is one of the most spectacular residents of deeper crevices under larger rocky offshore reefs and drop-offs. Often occurring as solitary individuals, and tending to be slow swimmers making small loops from deep within crevices. Juveniles are a paler blue, and can be almost white. Adults often curious and unafraid of divers.
Occurrence at the Busselton Jetty:
Rarely spotted from the underwater observatory windows.
