The predatory hawkfish are so called because of their habit of swooping down from the above on their victims, similar to the birds of prey.
Long pectoral fins enable these fish to rest securely on a rocky perch, so that although they may sway in the current, they will not be swept away by the swell. This is important as they lack a swim bladder, so they find it difficult in maintaining their buoyancy in the water.
