According to the Florida Museum of Natural History, the swordfish is widespread and mainly lives at medium depths in the tropical and temperate waters of the Indian, Pacific and Atlantic Oceans. However, the swordfish is commonly sighted near the ocean's surface and can tolerate waters of approximately 41 degrees Fahrenheit.
The swordfish is the lone member of the family Xiphiidae, differing from other billfish, such as the marlin. Swordfish can grow to lengths of 177 inches and weigh as much as 1,400 pounds. Pelagic fish compose the bulk of the swordfish's diet, although squid and cuttlefish also constitute a portion. The prominent bill of the swordfish is used to slash larger prey that can't be swallowed whole.
