Open encyclopedia reference
Notoscopelus kroyeri, commonly known as the lancet fish, is a species of lanternfish in the family Myctophidae. It is endemic to the North Atlantic Ocean where it is found in deep water habitats, spending its day at great depths and its night near the surface. It was previously regarded by some authorities as being a subspecies of Notoscopelus elongatus; one of the differences between the two being that N. elongatus has 25 or fewer gill rakers while N. kroyeri has 26 or more.
