Description

The latchet is a searobin (Triglidae) from the temperate coastal waters of southern Australia. The species has a flattened, bony head and large, fan-shaped pectoral fins that are conspicuously coloured when spread, sometimes with eyespot-like markings. The lower pectoral fin rays are free, finger-like feelers with which it 'walks' over the bottom and probes for prey. Adults live on the continental shelf; juveniles enter bays and estuaries. It feeds on small crustaceans and bottom animals. The species is harmless to humans.
