Myctophiformes

Myctophiformes is an order of ray-finned fishes that includes lanternfishes and several related families. Most species live in the open ocean, often at mesopelagic depths.

Actinopterygii: Actinopterygii is the class of vertebrates whose fins are supported by bony rays. Myctophiformes belongs to this vast class of ray-finned fishes.
Bioluminescence: Bioluminescence is the production and emission of light by living organisms through chemical reactions. It describes the light-making phenomenon behind many myctophid photophores.
Marine snow: Marine snow is sinking organic material, including detritus and fecal pellets, that carries carbon through the ocean. Lanternfish feeding and waste contribute to the movement of organic matter through the water column.
Northern lanternfish: Benthosema glaciale is a lanternfish found in the North Atlantic and adjacent Arctic waters. It is a common North Atlantic example of the family's midwater ecology.
Teleostei: Teleostei is the largest infraclass of modern bony fishes, characterized by a highly mobile jaw and a modified tail skeleton. The order sits within the teleost radiation.
Diel vertical migration: Diel vertical migration is the daily movement of aquatic organisms between deeper water by day and shallower water at night. Many lanternfishes rise toward the surface after dark to feed.
Biological carbon pump: The biological carbon pump is the ocean process that transfers carbon from surface waters to the deep sea through biological activity. Daily fish migrations can transport carbon downward through feeding and waste.
Glacier lanternfish: Benthosema glaciale is a lanternfish found in the North Atlantic and adjacent Arctic waters. Its high-latitude distribution illustrates the order's presence in cold northern seas.
Myctophidae: Myctophidae is the fish family commonly called lanternfishes, known for light-producing organs. This is the best-known family in the order and includes most its species.
Counterillumination: Counterillumination is camouflage produced by matching an animal's underside brightness to downwelling light. Ventral photophores can conceal lanternfishes from predators below.
