Family:  Aristeidae (gamba prawns)
Max. size:  4 cm CL (male/unsexed); 6.2 cm CL (female)
Environment:  benthopelagic; marine; depth range 60 - 1300 m
Distribution:  Atlantic, the Mediterranean and Indo-Pacific. Tropical to temperate.
Biology:  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). Maximum length is based on occurrence (Ref. 80237); to be replaced with a better reference. 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 (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 δ15N ranges from 6.68 and 7.96 in females, and 7.05 and 8.26 in males, with females having higher δ15N 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).
