In Finland's big natural open spaces, wild animals abound. Rare bird species live in the forests, as do bears, as well as no less than 55,000 moose and deer. The Teno River, located between the border of Norway and Finland, is home to many fish, especially Atlantic salmon whose weight can sometimes reach 55 pounds. The Turku archipelagos and other islands are crowded with pikes and perches, whereas trout prefer to live in rivers in the centre of the country.
