The Oilfish is a snake mackerel that remains the only species under its genus. It is usually confused with its relative named Escolar (Lepidocybium flavobrunneum) which contains a high amount of oil as well. The Oilfish is also related to bonitos, mackerels, tunas, and butterfishes, among others.
The Oilfish possesses large eyes, and a torpedo-shaped body covered in dark colored scales, making its skin rough. Its body is brown to dark brown with black tips on its pelvic and pectoral fins. It has 13 to 15 dorsal spines with 15 to 18 dorsal soft rays. It has no anal spine but has 15 to 18 anal soft rays.
Eating too much Oilfish causes keriorrhea which means “flow of wax”.
The Oilfish are carnivorous; they mostly feed on crustaceans, squid, and small fishes. Generally, they can eat anything easy enough to catch and small enough to devour.
Most Oilfish only measure up to 59 inches but they can grow up to 120 inches.
