Swordfish rely on their speed and agility as well as their special organs near their eyes These organs heat their eyes and brains and are believed to enhance their eyesight which improves their ability to catch prey.
Studies show they actually lose all scales and teeth before they reach adulthood.
Found in tropical to temperate waters of the Atlantic, Pacific and Indian Oceans near the surface of the open ocean.
They feed mainly on pelagic fish such as Mackerel, Barracudas, Silver Hake, Rockfish, Herring and Lanternfishes, with Squid and Crustaceans making up the remainder of their diet.
Like other Billfish, they will use their sword-like bill to slash and injure prey. It is also believed that they are used as a defensive spear to fend off predators.
When observed in the ocean, they are found alone or in loose groups separated by as much as 33ft.
Frequently found basking at the surface and airing their dorsal fin with the occasional leaping out of the water is a common sight as reported by many boaters.
They are the sole species (Xiphias gladius) in the Family Xiphiidae. Their biological physiology is actually quite different than that of other Billfish.
Swordfish are not a concern when it comes to vulnerability despite their popularity from sportfishermen.
