A swordfish (Xiphias gladius) is a large, highly migratory predatory fish characterized by a long, flat bill resembling a sword. They are found in tropical, subtropical, and temperate oceans worldwide and are a popular species for commercial and recreational fishing.
Physical Description
The most distinguishing feature of a swordfish is its long, flattened, and pointed bill, which is used to slash and stun prey. Their body is long and round, and they have a large dorsal fin and a forked tail. They are typically a dark, metallic purple or black on their back, fading to a lighter color on their belly.
Habitat and Diet
Swordfish are a solitary and highly migratory species. They are found in the open ocean at depths ranging from the surface down to over 1,800 feet. They are powerful and fast swimmers, able to reach speeds of up to 50 miles per hour in short bursts. Their diet consists of a wide variety of fish, squid, and crustaceans.
Behavior
Swordfish are known for their spectacular leaps out of the water, a behavior that is not fully understood but may be related to hunting or dislodging parasites. Their large eyes are specially adapted to see in low-light conditions, allowing them to hunt in the deep, dark waters of the ocean.
