Swordfish – 60 mph

The billfish, including the Swordfish, which gets its name from its long, flattened beak, or sword, is the very fastest fish in the oceans. The swordfish is torpedo-shaped, just like its siblings, and can move through the water at up to 60 miles per hour thanks to its long, compressed body. Although swordfish are ectothermic creatures, they have specific organs that heat their eyes and brains, just like some shark species. The recorded temperatures range from 10 to 15 °C (18 to 27 °F) above the ambient water temperature. Their vision is significantly enhanced by eye heating, which also enhances their capacity to capture prey.

Swordfish may reach lengths of 15 feet and weights of 1182 pounds. The second dorsal fin is much smaller and situated quite close to the first one, which is tall and curved. It can dive as deep as 198 feet and is found in open waters and close to the coast. It can be found in the Pacific from Oregon to Chile and the Atlantic from Newfoundland to Argentina.
