Bonapartia |
Gonostomatidae are a family of deep-water marine fish, commonly named bristlemouths, lightfishes or anglemouth. It is in class Stomiiformes, it is hence a form of ray-finned fish. It is a relatively small family, containing only 7 genera and 26 species.
The first fossile record of this family dates to the miocene epoch - and was discovered by L. S. Berg in 1958. The fish may be found in the Atlantic Ocean, Indian Ocean and Pacific Ocean, though species Cyclothone microdon may be found in Arctic waters. The look oddly long in appearance - and, most interestingly have photophores. These photophores are aligned along the bottom of the fish - or bottom of the head - emitting green or red light. Their chief common name - bristlemouth - is after their odd equally-sized bristle teeth. Due to the depth - very little light penetrates, resulting in almost pitch black states - as such, the fish is typically black to hide from prey.
