- Robust, torpedo-shaped body reaching up to 18 inches, among the largest flyingfish in its range
- Dark blue to blue-black back contrasting with silvery sides and belly
- Very large pectoral fins, typically plain dark or lightly speckled rather than sharply banded
- Enlarged pelvic fins that extend well past the midpoint of the body, aiding longer glides
- Deeply forked tail with a much longer lower lobe
Common look-alikes
- Tropical Two-wing Flyingfish: has only the pectoral fins enlarged, with small, unremarkable pelvic fins, unlike this species' long pelvic fins
- Bandwing Flyingfish: shows a distinct pale crossband on the pectoral fin that the California Flyingfish lacks
- Atlantic Flyingfish: occupies the Atlantic rather than the Pacific and tends to run smaller with proportionally shorter pelvic fins
Where you'll see one
Ranges through warm and temperate surface waters of the eastern Pacific, from California south along Baja and into Mexican waters, frequently observed gliding long distances above the swells offshore, especially during warmer months when it moves closer to shore.
Frequently asked questions
How do I tell the California Flyingfish from other two-wing flyingfish?
Check the pelvic fins in addition to the pectorals; the California Flyingfish has long pelvic fins that extend well down the body, functioning almost like a second pair of wings, unlike true two-wing species.
Is pectoral fin color useful for identifying this species?
Yes, a plain dark or lightly speckled pectoral fin without a pale crossband helps separate it from the Bandwing Flyingfish, which shows an obvious light band across the wing.
