Identification

The Crocodilefish is a species of flathead (family Platycephalidae) with an intricate pattern, a distinct pit immediately behind the eyes and a concave head margin.

The eyes of the Crocodilefish have iris lappets. These projections help break up the black pupil of the fish, and thus improve its camouflage (view underwater images, 1, 2, 3). Many other species of flatheads such as the Tasselsnout Flathead and Fringe-eye Flathead also have iris lappets.

Size range

The Crocodilefish grows to 54 cm in length.

Distribution

It occurs from the Philippines to New Caledonia.
