The black marlin (Makaira indica) is a species of
marlin found in tropical and subtropical Indo-Pacific oceans not far from the surface. It is a large commercial
game fish with a maximum published weight of 750 kg, but greater weights are known. It is one of the largest bony fish species. The black marlin's body is blue-black above, and a silvery white below, sometimes with light blue vertical stripes. The first
dorsal fin is blackish to dark blue with other fins dark brown with tinges of dark blue. The
pectoral fins cannot be folded back flat against the body. Black marlins primarily feed on
cephalopods and fish, especially
tuna, which they stun and kill with side to side slashing movements of their bill.
