The Gempylidae are a family of fishes that are called snake mackerels. They belong in the order Scombriformes. The family includes about 25 species.

These creatures are elongated fishes with a similar appearance to barracudas, having a long dorsal fin just like them. However, they are smaller. They have fangs like a barracuda.The largest species, including the snoek (Thyrsites atun), grow up to 2 m long, and the oilfish (Ruvettus pretiosus) can reach 3 m.
