The popular image of the swordfish skewering its prey with its nose is based on little evidence. In a typical environment, swordfish most likely use their noses to slash at prey and inflict weakening injuries. [6] The hypothesis that they may use their noses as spears in a defensive capacity against sharks and other predators is still under review.
Two species of Kansas Protosphyraena - the larger (about 3 m long) P. perniciosa and smaller P. nitida. In its general body plan, Protosphyraena resembled a modern sailfish, though it was smaller with a shorter rostrum, was somewhat less hydrodynamic, and adults possessed large blade-like teeth (adults of living swordfish species are toothless).
Xiphophorus is a genus of euryhaline and freshwater fishes in the family Poeciliidae of order Cyprinodontiformes, native to Mexico and northern Central America. Xiphophorus species can be divided into 3 groups based on their evolutionary relationships: platyfish (or platies), northern swordtails, and southern swordtails.
Needlefish (family Belonidae) or long toms [2] are piscivorous fishes primarily associated with very shallow marine habitats or the surface of the open sea. Some genera include species found in marine, brackish, and freshwater environments (e.g., Strongylura), while a few genera are confined to freshwater rivers and streams, including Belonion, Potamorrhaphis, and Xenentodon.

Swordfish (Xiphias gladius) are large, highly migratory, predatory fish characterized by a long, flat bill in contrast to the smooth, round bill of the marlins. Swordfish are elongate, round-bodied, and lack teeth and scales as adults. They are the sole member of their family Xiphiidae.

We spent the past two years testing and reviewing over 30 nose hair trimmers to find the best nose trimmers from brands like Panasonic, Philips Norelco, and Wahl.
The marlins are Istiophoriform fish, most closely related to the swordfish (which itself is the sole member of the family Xiphiidae). The carangiformes are believed to be the second-closest clade to marlins. Although previously thought to be closely related to Scombridae, genetic analysis only shows a slight relationship.
