Nansenia oblita, also called the forgotten argentine (from the specific name oblita, "forgotten") or the Mediterranean large-eyed argentine, is a species of fish in the pencil smelt family (Microstomatidae).

Description

Nansenia oblita is silvery in colour. Its length is maximum 18 cm (7.1 in). It has 10 or 11 dorsal soft rays, 9 or 10 anal soft rays, 28–30 gill rakers, 42–45 vertebrae, and 4 branchiostegal rays. The proximal part of the adipose fin is unpigmented and its entire body is covered with guanine. The base of the caudal and procurrent caudal-fin rays are pigmented.

Habitat

Nansenia oblita is pelagic, living in the northwest and eastern Atlantic Ocean, western Mediterranean Sea and Adriatic Sea at depths of 300–500 m (980–1,640 ft). It is commonly found off Messina, Sicily.

Behaviour

It spawns during winter in the Mediterranean, perhaps later in the Atlantic. It lays spherical eggs of about 1.5 mm (0.059 in) diameter. It feeds on zooplankton.
