Description

The longjaw leatherjacket (Oligoplites altus) is a jack of the eastern Pacific, from Mexico to Peru. It grows to 56 centimetres and lives in salt and brackish coastal water. The elongate, fairly deep and laterally compressed body is grey to brown above with silvery, yellow-tinted flanks. Distinctive is the large mouth whose upper jaw reaches beyond the eye; small, needle-shaped scales lie embedded in the skin. The dorsal fin spines connect to venom glands and can cause painful wounds. The fish is marketed fresh and salted or dried.
