Marlins are one of the fastest fish in the sea; able to reach short bursts of up to 68 mph.

They are characterized by their elongated body, a long, ridge-like dorsal fin, and their spear-like snout.

Most can be found in tropical to temperate oceans worldwide. They are pelagic and tend to live near the water’s surface.

They feed mainly on School Fish (Mackerel and Tuna,) and Squid.

They use their long bill to stun, injure or kill their prey by knifing through schools of fish.

They are highly migratory and will follow schools of fish for food.
