The species name, Xiphias gladius, derives from Greek ξιφίας (xiphias, "swordfish"), itself from ξίφος (xiphos, "sword") and from Latin gladius ("sword"). [6] This makes it superficially similar to other billfish such as marlin, but upon examination, their physiology is quite different and they are members of different families. [9]

The largest of the "requiem sharks" (in the genus Carcharhinus) seems to be the dusky shark (C. obscurus), at up to 4.2 m (14 ft) and a weight of 350 kg (770 lb). [32] However, the bulkier bull shark ( C. leucas ) has been estimated to weigh about 575 kg (1,268 lb) in recent specimens that measured over 4 m (13 ft) long. [ 33 ]
The Swordfish (Xiphias gladius) is a large oceanic apex predator inhabiting all the world's oceans. It is found in the entire Indian Ocean down to latitude 45°S.

Substantial numbers are caught incidentally by pelagic longline fisheries targeting more valuable species such as southern bluefin tuna (Thunnus maccoyii), swordfish (Xiphias gladius), and Patagonian toothfish (Dissostichus eleginoides), including vessels operated by Japan, Uruguay, Argentina, South Africa, and New Zealand.
