Surfperches are small (up to about 45 cm), ovate, laterally compressed fishes that occur mainly along the Pacific coast of North America. Other features include a small mouth, smooth scales, a forked tail, a single continuous dorsal fin of VI to XI spines and 9-28 soft rays, and anal fin with III spines and 15-35 soft rays.
The most notable characteristic of this family is their rather unusual mode of reproduction. Unlike other perciform fishes they have internal fertilization and bear their young alive. Breeding generally occurs in summer, but the gestation period is lengthy and birth of the young (up to 80 depending on species) does not occur until autumn or the following spring. The young are virtually mature at birth. Surfperches inhabit surge areas off sandy beaches, but are also found in kelp beds, tide pools, and sheltered bays and harbors. Food items include molluscs, crustaceans, and other small invertebrates.
This temperate region family contains about 24 species in 13 genera, all but two (from Japan and Korea) inhabit North Pacific. By far the most species occur along the coast of Southern and Central California; a single freshwater species is also found in California. Some species are ectoparasite "cleaners" of other fishes. The family was reviewed by Tarp (1952). A single representative, which is endemic to the eastern Pacific, occurs in our region in the Gulf of California.
