Blue Lanternfish

Description

A small, deep-sea lanternfish, *Diaphus coeruleus* is characterized by its bioluminescent organs (photophores) and large eyes adapted for low light. It is a mesopelagic species, performing daily vertical migrations between deep waters and the surface to feed. This species is not suitable for home aquariums due to its specialized deep-sea habitat requirements, including extreme pressure, cold temperatures, and specific light conditions.
