A viperfish is a deepwater fish with long, needle-like teeth and hinged lower jaws. Viperfish stay near lower depths ( 250–5000 feet) in the daytime and shallow at night. It is one of the fiercest predators in the very deep part of the sea and is believed to attack its prey by luring the victim close to itself with a light producing organ. This organ is called a Photophore and is located on the end of its dorsal spine. It uses its fang-like teeth to immobilise its prey, and would not be able to close its mouth because of their length if it were not able to curve them behind its head.
