Overview

Brief Summary

The Longnose Batfish (Ogcocephalus corniger) is named for its body shape.

Though all Ogcocephalus have a wide, triangularly shaped body, O. corniger has a

conspicuous long upturned rostrum (snout), present in just a few species, that is the

source of its common name. The pectoral fin is yellowish near the base and purplish

at the tip. The dorsal coloration consists of small, round, pale spots that are evenly

distributed over the body. A red-orange wash on the underside of the fish extends

to include the pelvic and anal fins. The lips are bright red-orange. (Bradbury 1980;

Robins and Ray 1986).

The genus Ogcocephalus is confined to the Western Atlantic and Eastern Pacific.

Ogcocephalus corniger is found in the waters of the southeastern United States and

the eastern Gulf of Mexico. This species exhibits a greater known depth range than

most other Ogcocephalus species, having been found from 30 to 250 meters.

Size may range from 26 to 134 mm SL (standard length, i.e., excluding tail). (Bradbury 1980).
