Ringed Seal


The Life of Animals | Ringed Seal | The ringed seal is the smaller and more common in the Arctic, with a small head, short muzzle like a cat and a plump body. The ringed seal taxonomy is discussed and reviewed in the literature. The ringed seal is very near the Caspian seal (P. caspica) and Baikal seal (P. sibirica), they all have the same relative sizes small, the functions of cranial morphology and affinity for ice actions.The closest phylogenetic relatives ringed seal, gray seal (Halichoerus grypus) and species in the genus Phoca (seals and sealing largha) when ringed seals were attributed above. along with the other northern latitude ice seals (seal, bearded seal, seals and hooded seals), these seals of the subfamily Phocinae

Ringed seals occur throughout the Arctic. You can, in the Baltic Sea, the Bering Sea and Hudson Bay. They prefer to rest on ice floe and continued north on thicker ice. In all the seas of the Arctic in the North Pacific, are found in the southern Bering Sea and range found as far south as the Seas of Okhotsk and Japan. In the assortment ringed seals have an affinity for ice-covered waters and ice to fill seasonal and permanent are great.

Distribution in Alaska Ringed seals in the Beaufort, Chukchi and Bering Sea, south of Bristol Bay in years of extensive ice cover. At the end of April to June ringed seals are distributed throughout their range from the south to the north of the ice edge. The preliminary results of recent studies in the Chukchi Sea in May and June were conducted in 1999 and 2000 indicate that ringed seal density is higher in the ice along the coast and fast package, and lower on sea ice. Ringed seals are found in Arctic waters and often with icebergs and ice, ringed maintains a hole in the ice to breathe so use the ice habitat is not connected, the other joints.Ringed seals are an important food source, especially for the polar bears. Early Paleo Eskimo sites in the Canadian Arctic ringed seals signs harvested from about 4000-3500 BP, probably frozen tears and bears trapped in the ice, with an option for adolescents and young adults.

The bycatch in fishing nets, trawls and trade is another threat to ringed seals. Climate change is the greatest potential threat to ringed seal populations because much depends on their habitat Birthing ice caves are often destroyed before the seal is able to feed itself in a poor physical condition was.
