Length at first maturity / Size / Weight / Age

Maturity: L_m ? range ? - ? cm Max length : 170 cm TL male/unsexed; (Ref. 1394); 160 cm TL (female); max. published weight: 123.0 kg (Ref. 1394)

Inhabit the southern edges of the pack ice from winter to early summer and coastal areas including river mouths, in late summer and autumn. Diet composition varies with the age of the seal; Newly weaned pups feed on small crustaceans, advance to schooling fishes, larger crustaceans, and octopuses, and finally graduate to bottom dwelling fish and cephalopods (Ref. 1394).

Those in their first year tend to eat mostly small crustaceans, algae, sticks and debris; 1 to 4 year olds mostly eat fishes, larger shrimps, and octopus, occasionally; 5 year olds consumed more benthic invertebrates like crabs and octopus (Ref. 119414).
