They feed nocturnally on crustaceans and small fish.

Flatheads are closely related to Scorpionfish.
Their eyes are covered by a tasselled curtain which helps to disguise them from predators. The tassels expand and contract with intensity of light. Ref: https://www.fishbase.se/summary/Onigocia-spinosa.html
