Environment: milieu / climate zone / depth range / distribution range
Benthopelagic; depth range 60 - 1300 m (Ref. 97594), usually 250 - 750 m (Ref. 409). Tropical; ? - 14°C (Ref. 434), preferred 20°C (Ref. 107945); 55°N - 55°S, 180°W - 180°E
Atlantic, the Mediterranean and Indo-Pacific. Tropical to temperate.
Length at first maturity / Size / Weight / Age
Maturity: Lm 3.7, range 3 - 4.414 cm Max length : 17.0 cm TL male/unsexed; (Ref. 104052); 22.5 cm TL (female); max. published weight: 45.90 g (Ref. 126095); max. published weight: 45.90 g; max. reported age: 8 years (Ref. 80203)
Deep-water benthopelagic shrimp (Ref. 114287). Common total length: 12 to 16 cm. Minimum common depth from Ref. 8. Usually caught on muddy and sandy bottoms of continental slopes (Ref. 434). Lives on bottom mud (Ref. 8); also on sandy bottoms. Moves to midwater at night (Ref. 409). Carnivorous, feeds mainly on euphausiids and other species of crustaceans, i.e., mainly Natantia sp. (Ref. 434). Has a highly diversified diet (Refs. 97770, 105137), preying on pelagic, benthic and benthopelagic organisms (Ref. 105137); mainly forages on crustaceans and fish. Also scavenges upon carcasses of fish and cephalopods on the bottom (Ref. 97770). Exhibits cannibalism. Values of ╬┤15N ranges from 6.68 and 7.96 in females, and 7.05 and 8.26 in males, with females having higher ╬┤15N with increasing size (Ref. 105135). Females were more abundant than males in summer and spring in all depth strata and during autumn on the deepest bottoms while males were around 50% and outnumbered females above 500 m during autumn and winter, respectively (Ref. 80203).
