Ringed Seal

The ringed seal is the smallest northern true seal, with a short muzzle, compact body and coat patterned by pale rings against a darker grey back. Adults are usually about 1.1–1.5m long and weigh around 50–70kg. Strong claws on the foreflippers maintain breathing holes through sea ice, an adaptation central to the species' winter survival (NOAA Fisheries species account). The streamlined body narrows toward the hind flippers.

Across its circumpolar range, the species depends closely on seasonal sea ice. Females excavate snow-covered lairs above breathing holes and give birth to a single white-coated pup inside. Ringed seals feed on fish and crustaceans, with prey varying by region and season. They are often solitary and remain widely dispersed where suitable ice and breathing holes are available (NOAA Fisheries species account).
