Veiled anglemouth

The veiled anglemouth (Cyclothone microdon) is a small deep-sea fish in the bristlemouth family Gonostomatidae. It is abundant in all of the world's oceans, living at depths of about 300 to 2,500 metres,. The largest known specimen measures 7.6 centimetres. Its common name refers to its circular mouth filled with small teeth, and the genus name Cyclothone means in a circle or around, while microdon means small teeth. The body is brown to black, with a radiating pigment over the head and fins that the article describes as bioluminescent. The International Union for Conservation of Nature has assessed the species as Least Concern because of its abundance in most oceans and the small effect human activity has on its population growth. FishBase records it as a species of the deep mesopelagic and bathypelagic zones that feeds mainly on copepods and is of no interest to fisheries.
