Abstract
Billfishes are one of the apex predators in the pelagic food chain, distributed worldwide in the epipelagic waters of tropical and subtropical oceans. These fishes can disperse widely throughout the world oceans and spawn over broad geographic regions during a protracted season (Nakamura 1985). Billfishes are commonly seen within 200 m of the ocean water layer above thermocline but the occurrence up to 800 m is also reported. They are characterized by a prolonged upper jaw forming a long rostrum called bill and using the long bill to attack and stun their prey by moving their heads in various directions to make the prey unconscious and form a hassle-free prey capture. Sexual dimorphism is reported in billfishes with large sized females.
