Description

The longspine flathead is a flathead (Platycephalidae) from the waters around Australia. The species has a strongly flattened head and an elongate body, with prominent spines on the gill covers, and high-set eyes. It lies half-buried on soft bottoms of coastal waters and is an ambush hunter that takes passing small fishes and crustaceans. It is not venomous, but the sharp head spines can give a wound when handled.
