Amphelikturus
Amphelikturus is a genus of small, deep-sea fish in the family Gonostomatidae. These fish are commonly known as bristle mouths or lightfishes. They are characterized by their elongated bodies, large eyes, and numerous photophores (light-producing organs) scattered along their bodies.
Common Names
Amphelikturus species are commonly referred to as bristle mouths or lightfishes.
Characteristics
Members of this genus are small, slender fish with elongated bodies. They have large eyes adapted for seeing in the low-light conditions of the deep sea. Amphelikturus species are distinguished by the presence of numerous photophores, which emit a bioluminescent light. These photophores are scattered along the body, including the head, belly, and flanks. The arrangement and number of photophores can vary between species and are important for identification.
Environment
Amphelikturus species are found in the deep ocean, typically at depths of 500-2,000 meters (1,600-6,600 feet). They inhabit the mesopelagic zone, also known as the twilight zone, where sunlight is limited but still present. This environment is characterized by low temperatures and high pressure.
