Description
The Deepsea Loosejaw, *Malacosteus niger*, is a predatory deep-sea fish characterized by its unique hinged jaw and lack of a floor in its mouth, allowing it to swallow large prey. It possesses red light-emitting photophores, invisible to most other deep-sea creatures, aiding in hunting. This species is found in the bathypelagic and abyssal zones of the world's oceans and is not suitable for home aquaria.
