The second dorsal and anal fins extend almost to the tail and the pectoral fins are large and paddle shaped. The gill covers have a long spine pointing backwards. The fish is yellowish brown with a paler underside.

    Additional information icon Additional information The spines of the first dorsal fin and gill covers release a poison that give an extremely painful sting to bathers or fishermen treading on the buried fish. The name weever is derived from the Anglo-saxon word meaning viper and reflects the venomous nature of the fish.
