Agujon needlefish (Tylosurus acus acus) live in the western Atlantic Ocean and Gulf of Mexico from Florida to Brazil and in tropical and sub-tropical waters around the world. They grow to six or seven pounds and four feet in length and are usually found as part of coral reef ecosystems, feeding on the smaller fish. Agujon needlefish are caught by sport and artisanal fishermen. Because their bones have a greenish color, there is a limited market except in Puerto Rico where they are a popular delicacy. They are one of the fifty members of the family Belonidae, all of which bear a resemblance to gar because of their long bodies and beak-like jaws with sharp teeth.
