Electrona is a genus of lanternfishes in the family Myctophidae.
There are currently five recognized species in this genus:[2][3]
Electrona lanternfishes are small, discoid fishes.
While Electrona risso can be found throughout the world, widespread in the Indian, Pacific, Atlantic Oceans, and Mediterranean, the other four species are limited to the southern hemisphere, mostly limited to the Southern Ocean. Their dispersion is dependent on the balance between current-mediated larval dispersal and adult active homing behavior.[4] Besides E. rissoi is E. paucirastra the only species that is found north of the Southern Ocean.E. antarctica mainly inhabits the Antarctic deep and therefore warmer waters.[5] E. carlsbergii inhabits the water south of the Antarctica convergence to the Antarctic coast, and between the Antarctic and sub-Antarctic convergences.[5] Larval forms of many deep-water species are found to inhabit inshore waters.[6] Migration patterns vary between different species, size groups, life history stages, sex, latitude, time and season.[6]
These fish exhibit a daily migration pattern. During the day they concentrate between 400–1000 m.[6] During the night, they migrate close to the surface between 5–100 m. These diel vertical migrations are primarily performed because zooplankton, their main food, is concentrated in the upper layers, while they need to go deep during the day in order to avoid predators.[6]
Electrona have a low fecundity. Females produce eggs the size of 0.7-0.9 mm.[6] Spawning of some species may occur any time during the year. In the Arabian Sea, fish spawn during all seasons but significantly increases during monsoon transition periods (March–June and September–November).[6] The larva exhibit diversity with their shape not similar to the adult and the larvae have a highly stalked eye and trailing intestine.

Electrona è un genere di pesci ossei marini appartenenti alla famiglia Myctophidae.
Le specie del genere sono diffuse nell'Oceano antartico e nelle basse latitudini dell'emisfero australe, con l'eccezione di Electrona risso, presente in tutti i mari e gli oceani del globo, mar Mediterraneo compreso. Sono pesci abissali con abitudini batipelagiche, come la maggioranza dei Myctophidae.
Sono pesci di piccole dimensioni, con lunghezze massime che variano dai 7 ai 12 cm, secondo la specie.

남극발광샛비늘치속(Electrona)은 샛비늘치과에 속하는 조기어류 속의 하나이다.[1] 작은 원반 형태의 물고기이다. 발광샛비늘치(E. risso)는 인도양과 대서양, 지중해 등 전세계에 널리 분포하지만, 나머지 4종은 남반구에 제한적으로 서식한다. 매일 서식 공간을 옮기는 패턴을 보인다. 낮 동안에는 수심 400~1,000m에 집중적으로 서식하고 밤에는 수심 5~100m의 해수면 가까이로 올라온다.
