Euphausiidae
Environment: milieu / climate zone / depth range / distribution range
Ecology
Pelagic; depth range 0 - 300 m (Ref. 138633), usually 15 - 130 m (Ref. 111951). Polar, preferred -1°C (Ref. 107945); 48°S - 78°S, 180°W - 180°E
Circumpolar in the Southern Ocean: from eastern Ross Sea to the Antarctic Peninsula and Weddell Sea, north to Kerguelen Islands, east to western Ross Sea.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 3.0 cm TL male/unsexed; (Ref. 101405)
Minimum depth based from Ref. 111951. Found along most of the Antarctic coastline. Adult krill populations' center of distribution is near the continental shelf break, juveniles are found in inshore waters and the eggs and larvae are found in offshore waters (Ref. 96896).
