Flyingfish (lat. Cypselurus heterurus)
OTHER NAMES:
French: exocet;
Spanish:
volador.
Flyingfish are members of the Exocoetidae family and are
closely related to halfbeaks, balao, and needlefish. The flyingfish
has normal-length jaws, unlike these other species;
the fins are soft rayed and spineless; and the lateral line is
extremely low, following the outline of the belly. The dorsal
and anal fins are set far back on the body. The pectoral fins
of flyingfish are greatly expanded, forming winglike structures.
The round eggs are generally equipped with tufts of
long filaments that help to anchor the eggs in seaweeds.
These fish travel in schools and are abundant in warm
seas. They are an important food fish for pelagic species,
especially for billfish, and may be used as rigged trolling
bait for bluewater fishing. Flyingfish are readily observed
in offshore environs when they suddenly burst through
the water’s surface and glide for a short distance before
reentering the water.
About 22 species are found off the Atlantic and the
Pacific coasts of North America. The largest of all North
American flyingfish is the California flyingfish (Cypselurus
californicus), which may be 11⁄2 feet long. It is found only off
the coasts of Southern California and Baja California. It is
one of the “four-winged” flyingfish, because the pelvic, as
well as the pectoral, fins are large and winglike.
The common Atlantic flyingfish (C. heterurus; also C.
melanurus), found in warm waters throughout the Atlantic,
is two-winged, with a black band extending through the
wings. It averages less than 10 inches in length.
Other common species of warm Atlantic and Caribbean
waters are the margined flyingfish (C. cyanopterus), the
bandwing flyingfish (C. exsiliens), and the short-winged
flyingfish (Parexocoetus mesogaster), the latter ranging
through all warm seas and noted for shorter wings than
found in most species.
