The black marlin is a giant of the ocean, measuring up to 13 feet in length and weighing up to 1,500 pounds. The fish cruises the Pacific and Indian oceans in search of smaller fish to devour, and sometimes uses its spear-like upper jaw to stun its prey.

The power and size of this athletic fish make it a prize for sport fisherman, and the marlin's strength and capacity for struggle was famously celebrated in Ernest Hemingway's novella, The Old Man and the Sea.
