Most are marine, though a few needlefish and halfbeaks inhabit brackish and fresh waters. Perches, halfbeaks, Carangidae, needlefish and rays are also caught near the reefs. Belone is a genus of needlefish common in brackish and marine waters. It feeds on pelagic fishes such as needlefish, tuna, and jack, as well as squids. The houndfish is replaced by the Mexican needlefish, in the eastern Pacific. The living animals would have superficially resembled modern-day needlefish or houndfish. There are surface swimmers, subsurface swimmers, needlefish, poppers, pencil poppers, and darters. They are named after the "bigiw", the local name for needlefish, due to its shape. Keeltail needlefish, like all needlefish, closely resemble North American freshwater gars (family Lepisosteidae). Occasional deaths and serious injuries have been attributed to needlefish. Flat needlefish are found worldwide in tropical and temperate seas. Tylosurus is a genus of needlefish, one of ten in the family Belonidae. Needlefish reproduce through mating and lay eggs. The keel-jawed needlefish is widespread in the Atlantic and Indo-Pacific oceans. Needlefish are slender, ranging from in length.
