Appearance
An adult saimaa ringed seal is between 85 and 160 cm in length and weighs between 40 and 90 kg; males usually being larger than females. They are coloured dark gray, with a gray-black dorsal with circular white rings. The bottom is light gray. The saimaa ringed seal is darker in color than other ringed seals.
Reproduction Saimaa ringed seals become mature between the ages of 3 and 7. Their pregnancy rate is between 80 and 95 percent. Ringed seals' gestation lasts between 10 and 11 months. Their pups are between 55 and 65 cm, and 4 to 5 kg at birth. The saimaa ringed seals' longetivity is 40 years. With the current population level, between 18 and 26 pups are born every year.
Conservation The Saimaa ringed seal has been protected singe 1955. In 1983, the population was between 100 and 150 seals. In 2005, it is about 270. It is thought that the immediate threat of extinction would be alleviated if the population grew to over 400 individuals. In order to protect the Saimaa ringed seal, fisheries have been banned from their living areas. Also, it is forbidden for unauthorised people to go to the islands where these seals live. The Saimaa ringed seal lives nowadays mainly in two Finnish national parks, Kolovesi and Linnansaari Kolovesi National Park (Koloveden kansallispuisto) is a national park in Eastern Finland. ...
