Open encyclopedia reference
The veiled anglemouth (Cyclothone microdon) is a bristlemouth of the family Gonostomatidae, abundant in all the world's oceans at depths of 300–2,500 meters (980–8,200 feet). Its length is 10–15 cm (4–6 in) though the largest known specimen is 7.6 cm (3.0 in). It gets its name from its circular mouth, filled with small teeth: the name "cyclothone" means in a circle or around and "microdon" means small teeth. The International Union for Conservation of Nature (IUCN) has assessed the veiled anglemouth is of Least Concern due to its abundance in most oceans and the little effect human impact has on its population growth. Some of the veiled anglemouth's physical features include a brown to black body with a radiating, or expansive, bioluminescent pigment over its head and fins.
