On this Wikipedia the language links are at the top of the page across from the article title. This article is about a type of fish. They are the sole member of their swordfish sous vide, Xiphiidae. The swordfish is named after its long pointed, flat bill, which resembles a sword.

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. Several extinct genera are known, such as a large sized Xiphiorhynchus and Aglyptorhynchus. Unlike modern taxa these have equally long lower jaws. The popular belief of the “sword” being used as a spear is misleading. Their nose is more likely used to slash at its prey to injure the prey animal, to make for an easier catch. The use as an offensive spear in case of dangers against large sharks or animals is under review.
