(''C. oxycephalus'') extending into the eastern Pacific. These fishes are associated with coral and rocky habitats.


Biology

''Cirrhitichthys'' hawkfishes are predatory, using the "sit and wait" technique to ambush benthic prey which can be invertebrates or fish, perching on their thickened lower pectoral fin rays among sponges and corals. They are protogynous hermaphrodites, all start out as female and live in harems, if the male is lost the largest and more dominant female will change sex. They are pelagic spawners rising upwards into the water column in pairts to spawn.


Utilisation

''Cirrhitichthys'' hawkfishes are collected for the aquarium trade.
