As their name indicates, the head, which is large and covered with ridges and spines, and the forward part of the body are flattened from top to bottom. The fish are carnivorous and generally live on the ocean bottom, buried beneath the surface. They are commercially valuable food fish and reach a maximum of about 1.3 metres (50 inches) and 15 kg (33 pounds).
