The two main subspecies of sailfish, Atlantic and Indo-Pacific, range throughout the warm and temperate parts of the world’s oceans. They are blue to gray in color with white underbellies. They get their name from their spectacular dorsal fin, known as a sail, that stretches nearly the length of their body and is much higher than their bodies are thick.
Another notable characteristic is the elongated bill, resembling that of the swordfish and other marlins. Their meat is fairly tough and not widely eaten, but they are prized as game fish. These powerful, streamlined beasts can grow to more than 10 feet (3 meters) and weigh up to 220 pounds (100 kilograms). The BGFA record for this species of fish is 78.3 pounds however.
