Short description आकृति विज्ञान
Sexually dimorphic. Coloration when dry is pale yellow to light tan with dark brown undersides and near their flippers. When wet, color is grayish white. Pelage is short coarse hairs. Mature males develop a prominent mane on the necks and chests, with heads that are more robust with a flatter snout than females.
Inhabits coastal and immediate offshore waters (Ref. 1522). Preyed upon by great white sharks (Ref. 32140). Coastal and immediate offshore waters (Ref. 1522). Non-migratory but may disperse considerably from breeding sites. Appears to feed along the continental shelf and break (Ref. 80660). Found from the coast to the outer continental shelf; they frequent deep oceanic waters in some parts of the range. Feeds on many varieties of fish and squid, prefers bottom species; feeding occurs at night (Ref. 1394).
Life cycle and mating behavior परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | Eggs | Fecundity | Larvae
Only sexually mature Steller sea lions return to rookeries, except for few dependent young with their mothers. Gestation results only one pup which is nursed for under a year up to 3 years. Mothers stay on shore with their newborn for about a week before leaving for regular feeding trips. Copulation usually occur prior to first feeding trip. Longevity lasts about 14 years for males and 22 years for females, with a generation time of 10 years.
