Distribution and habitat

It lives in the Eastern and Western Atlantic, near areas like Portugal, Liberia, Angola, South Africa, Brazil, and the eastern Mediterranean. It is found from depths from 0 to 1,450 m (0 to 4,757 ft) below the surface, usually at 425 to 650 m (1,394 to 2,133 ft) below the surface. During the day it is in waters from 425 to 1,000 m (1,394 to 3,281 ft) deep,[2] and can be up to 200 m (660 ft) deep at night to feed.[3]

Description

G. cocco can reach a length of up to 6 cm (2.4 in). It has 10 to 13 dorsal soft rays, and 21 to 23 anal soft rays. Mature males have 6 to 8 supracaudal luminous structures, while mature females only have 3 to 6.[2]
