A viperfish is any species of marine fish in the genus Chauliodus. Viperfishes are mostly found in the mesopelagic zone and are characterized by long, needle-like teeth and hinged lower jaws. A typical viperfish grows to lengths of 30 cm (12 in). Viperfishes undergo diel vertical migration and are found all around the world in tropical and temperate oceans. Viperfishes are capable of bioluminescence and possess photophores along the ventral side of their body, likely used to camouflage them by blending in with the less than 1% of light that reaches to below 200 meters depth.[2]
Although it may appear to be covered in scales, viperfishes do not possess scales. Rather, they are covered by a thick, transparent coating of unknown substance.[3] Extremely large, fang-like teeth give the fish a slightly protruded lower jaw.
