Tag Archive: Hawkfishes


TAXOMONY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-like)
Family: Cirrhitidae (Hawkfishes)

Genus/species: Oxycirrhites typus

GENERAL CHARACTERISTICS: Color is whitish with horizontal and vertical red bands forming a cross-hatch pattern. The body is slender, moderately compressed with a long snout (~ ½ head length). The upper head profile slightly concave with a fringe of cirri on rear edge of front nostril.

Length up to 13 cm (5 in)

NOTE: These two fish are a pair and were collected together in the Philippines (2015) at 250 ft per Charles Delbeek, California Academy of Sciences.

DISTRIBUTION/ HABITAT: Widely distributed throughout the Indo-Pacific and Red Sea. Also found in the eastern Pacific from the Gulf of California to northern Columbia and the Galapagos Islands. They are non-migratory tropical marine fish, found at depths from 10–100 m. Inhabit the steep outer reef slopes that are exposed to strong currents. They are usually found in large gorgonians and corals.

DIET IN THE WILD: O. typus feeds on small benthic or planktonic crustaceans. This long mouth allows the fish to reach into small crevices to capture shrimp and remove snails from their shells.

REPRODUCTION: Monogamous pelagic spawner

CONSERVATION: IUCN Red List Not Evaluated

REMARKS: Members of this family seem to be monogamous. However, in reality they probably practice facultative monogamy. In this mating system, males are limited in their ability to acquire and maintain females, and thus have only a single mate, but may acquire additional females if conditions for doing so are favorable.
