California Flyingfish

The California Flyingfish (Cheilopogon pinnatibarbatus californicus) is a large subspecies of flyingfish in the family Exocoetidae, recognized as one of the biggest flyingfishes in the eastern Pacific. It ranges along the warm coastal and offshore surface waters of the eastern Pacific from central California south through the Gulf of California and Mexico. Like other Cheilopogon species, it is a "four-wing" flyingfish, using both enlarged pectoral and pelvic fins to glide above the ocean surface. It is an important forage species for tunas, dolphinfish, seabirds, and other pelagic predators. The species is common and not considered threatened.

Field marks of the California Flyingfish:

• Stout, torpedo-shaped body, among the largest flyingfishes, reaching roughly 30-45 cm
• Dark blue-black dorsal coloration contrasting with silvery sides and belly
• Very large, mottled dark pectoral fins used as primary gliding wings
• Smaller but still enlarged pelvic fins forming a secondary pair of wings
• Deeply forked tail with an elongated lower lobe used to power surface takeoffs

Its notably large size relative to other eastern Pacific flyingfish, combined with the four-wing fin arrangement, helps separate it from smaller two-wing species such as Exocoetus. Close relatives in the Cheilopogon genus require examination of fin coloration and body proportions to distinguish reliably.

California Flyingfish live near the surface of warm offshore and coastal waters of the eastern Pacific Ocean, from around central California south through Baja California, the Gulf of California, and into Mexican waters, generally favoring sea temperatures above about 18°C. As an epipelagic species, it spends its life in the upper few meters of open water, often well offshore over deep water, though it can be encountered closer to shore during warm-water periods. Its distribution shifts seasonally and during warm-water events, sometimes extending its range further north.

Like other flyingfish, the California Flyingfish escapes predators by building speed underwater, breaking the surface, and spreading its large wing-like fins to glide for extended distances, using rapid tail beats against the water to extend or redirect flight. It typically occurs in loose surface aggregations and feeds on planktonic organisms filtered from the water column. It is an important prey item for tunas, billfish, dolphinfish, and seabirds throughout its range. Spawning occurs in warm surface waters, with eggs bearing sticky filaments that attach to floating algae or debris until hatching.
