The temperate marine flatheads can be quite a challenge to identify. The Bluespotted Flathead usually has scattered blue spots on the back and a distinctive pattern of dark blotches on the tail.
The Bluespotted Flathead can be recognised by its sandy colour, scattered blue spots, and the series of elongated dark blotches on the tail. The blotches become progressively larger towards the bottom of the fin. The lower preopercular spine is distinctly longer than the upper.
The Bluespotted Flathead is found on sandy bottoms from shallow coastal bays and estuaries to well offshore.
The species is officially recorded from southern Queensland to eastern Victoria but may occur as far west as eastern South Australia.
