The term billfish is applied to a number of different large, predatory fish characterised by their large size (swordfish can be over 4 metres long) and long, sword-like bill. Billfish span the sailfish and marlin, which make up the family Istiophoridae, and the swordfish, sole member of the family Xiphiidae. They are important apex predators feeding on a wide variety of smaller fish and cephalopods.
