TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Actinopterygii (ray-finned fishes)

Order: Perciformes (Perch-likes)

Family: Embiotocidae (Surfperches)

 

Genus/species: Hypsurus caryi

 

GENERAL CHARACTERISTICS: Compressed and oval to oblong-shaped body. Base coloration is usually silver, and some species have stripes or bars, which may be dependent on the time of year (breeding vs. non-breeding coloration) and whether the fish is a juvenile or adult. Fins tinged with orange with black blotch on continuous soft dorsal and anal fins. The caudal (tail) fin is forked.

 

Maximum fish length per species ranges from 4 to 18 inches.

 

DISTRIBUTION/HABITAT: Cape Mendocino to northern Baja California along rocky shores, often at the edges of kelp beds; occasionally over sand but not found in the surf zone.

 

DIET IN THE WILD: Rainbow Surfperch feed on isopods, amphipods and other crustaceans; also snails and brittle stars.

 

REPRODUCTION: H. caryi males approach the female from below; both swim with vents close for 2 or 3 seconds, then separate and repeat the process. As all surfperch H. caryi fertilization is internal and are viviparous (livebearers) giving birth to as many as 22 young which are fully-formed 5 cm (2 in) at birth miniature versions of the adults.

 

COSERVATION: IUCN: Not evaluated.

 

REMARKS: Divers in Monterey Bay report rainbow surfperch cleaning ocean sunfish (Mola mola).
