Cutlassfish is a type of saltwater fish with a long, slender body that tapers to a hairlike tail. Cutlassfish live in all warm seas and are abundant in the Caribbean and the Gulf of Mexico. These fish have a large mouth with four large barbed fangs in the upper jaw and two in the lower jaw. Most cutlassfish measure about 21/2 feet (75 centimeters) long, but some grow as long as 5 feet (150 centimeters). Cutlassfish living off the coast of Japan lay their eggs in fairly shallow waters. The fish are caught for food in some areas.
