Wild forest reindeer (Rangifer tarandus fennicus) The reindeer is the only deer where both sexes grow antlers. The wild forest reindeer is a sub-species of the mountain reindeer and adapted for a life in the forest. It has considerably longer legs, broader hoofs and a smallet antler crown than the mountain reindeer. The wild reindeer became extinct in our country in the 1860s, and 50 years later (1915) it was placed under protection. "Swedish" reindeer are now domesticated and herded by the Sámi.
