Description

The slender hakeling is a slim, hake-like deep-sea fish of the family Merlucciidae reaching about 53 cm. The elongate, silvery body has large eyes, a pointed head with a fairly large mouth and a body that tapers strongly backward; the species is related to the hake but much more slender and smaller. It lives meso- to bathypelagically in the open water above the continental slope of the Atlantic, usually between one hundred and fifty and one thousand metres. It feeds on small zooplankton and small fish. Because of its life in the deep open water it is only rarely observed and has no fishery importance; it is known mainly from a few catches in deep-sea research.
