Etymology: Benthosema: Greek, benthos = depth of the sea + Greek, sema, sematos = signal, flag (Ref. 45335).
Environment / Climate / Range
Marine; bathypelagic; depth range 10 - 300 m (Ref. 4066). Deep-water, preferred 26°C (Ref. 107945)
Indo-West Pacific: Arabian Sea to about 25°S off Mozambique and to the western Pacific region. Occurrence in the northwest Pacific and eastern Indian Oceans need confirmation (Ref. 9835). Southeast Atlantic: Larvae were present in cruise collections off the eastern coast of South Africa, however, adults have not been reported in this area (Ref. 41388).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.0 cm TL male/unsexed; (Ref. 9835)
Benthopelagic and mesopelagic in slope and near continental and island waters (Ref. 9835, 11230). Found in 130-300 m during the day and in 10-200 m at night (Ref. 4066). Feeds in the evening (Ref. 9191). Feeds on mainly on copepods and various crustacean larvae. Lipid content is 4.6 % in fresh body weight (Ref. 8966).
