Bathylagidae (Deep-sea smelts)
Etymology: Bathylagus: Greek, bathys = deep + Greek, lagos = hare (Ref. 45335). More on author: Günther.
Environment / Climate / Range
Ecology
Marine; bathypelagic; depth range 0 - 4000 m (Ref. 5002). Deep-water, preferred ?; 45°S - 74°S
South Atlantic, Indian and Pacific. Southern Ocean: circum-Antarctic.
Length at first maturity / Size / Weight / Age
Maturity: Lm 11.2 range ? - ? cm
Max length : 14.0 cm SL male/unsexed; (Ref. 5002); 17.0 cm SL (female)
Some studies on feeding have shown that euphausiids comprised 46% by weight of the food consumed by this species. Spawning probably occurs 3-4 times a year (Ref. 5002).
