Valenciennellus tripunctulatus, commonly called the constellationfish,[3] is a species of fish in the family Sternoptychidae (hatchetfish).[4][5][6]

Description

[edit]

Valenciennellus tripunctulatus is small, growing no longer than 3.1 cm (1.2 in).[7] It darkens its body at night by pigment dispersion. It is silvery-white in colour with several black spots; the name tripunctulatus ("three-spotted") refers to the larger spots on their ventral surface, although there are often more than three of these.[8]

Habitat

[edit]

Valenciennellus tripunctulatus lives all the world's non-polar oceans. It is bathypelagic and non-migratory, living at depths of 100–1,000 m (330–3,280 ft).[7][9]

Behaviour

[edit]

Valenciennellus tripunctulatus is a selective daytime feeder on copepods (mainly Pleuromamma) and ostracods (such as Conchoecia).[10]

It breeds year-round, with egg batches about 100–360 eggs per ovary pair, the number increasing with animal size.[7] It does not guard its eggs.[11]
