Freshwater Pinniped
Freshwater seals are pinnipeds which live in freshwater bodies. The group is paraphyletic in nature, the uniting factor being the environment in which these pinnipeds live. The vast majority of all modern seals live solely in saltwater habitats though this is likely due to the rarity of sufficiently large freshwater bodies rather than the limitation of seal biology. Baikal seals The only exclusively freshwater seal species is the Baikal seal, locally named (). The Baikal seal has inhabited Lake Baikal for roughly two million years, the closest relative to it being the Arctic ringed seal whence it has likely descended. The manner by which the baikal seal reached Lake Baikal is still not fully understood, theories include their entrance into the lake via travel up the Yenisei River or perhaps via large lakes which existed in Siberia during the Pleistocene. Ringed seals While the Baikal Seal may be the only unique species of pinniped to live in a purely freshwater environmen ...

Common Seal
The harbor (or harbour) seal (''Phoca vitulina''), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. The most widely distributed species of pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic and Pacific oceans, Baltic and North seas. Harbour seals are brown, silvery white, tan, or grey, with distinctive V-shaped nostrils. An adult can attain a length of 1.85 m (6.1 ft) and weigh up to . Blubber under the seal's skin helps to maintain body temperature. Females outlive males (30–35 years versus 20–25 years). Harbor seals stick to familiar resting spots or haulout sites, generally rocky areas (although ice, sand, and mud may also be used) where they are protected from adverse weather conditions and predation, near a foraging area. Males may fight over mates under water and on land. Females bear a single pup after a nine-month gestation, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

It is the easternmost region of Finland and shares a border with Russia. The city of Joensuu is the capital and the largest settlement of the region. North Karelia has successfully reduced chronic diseases through public health measures. In the 1960s Finland led industrialized nations in heart disease mortality rates; North Karelia had Finland's highest incidence. In 1972 a long-term project was undertaken which targeted this risk in North Karelia. The resulting improvement in public health is still considered remarkable, a model for the rest of the nation. North Karelia is also known as the most sociable region in Finland. History The borders of remote North Karelia were formed gradually.
