description Stareater (Astronesthes gemmifer) Overview
The stareater, scientifically known as Astronesthes gemmifer, is a species of deep-sea fish belonging to the family Stomiidae. It possesses rows of gem-like photophores along its body that produce bioluminescence, which is used for counter-illumination to avoid predators and to attract prey in the darkness. Like many species in the dragonfish family, it features a large mouth equipped with sharp, fang-like teeth and a bioluminescent chin barbel used as a lure. This species primarily inhabits the mesopelagic and bathypelagic zones of tropical and subtropical oceans worldwide.
