Reindeer evolved during the last ice age to withstand temperatures as low as minus 94°F (minus 70° C. Yes, you read that right. This is an amazing feat, accomplished only by a select group of ...
Reindeer’s cloven hooves are well adapted to survive the cold. During colder months, a reindeer’s hooves toughen up, allowing them to step on frozen, harsh terrain. Their eyes are adapted to ...
Reindeer hooves adapt to the season: in the summer, when the tundra is soft and wet, the footpads become sponge-like and provide extra traction. In the winter, the pads shrink and tighten, exposing the rim of the hoof, which cuts into the ice and crusted snow to keep it from slipping.
Reindeer are a species of deer also known as caribou in certain regions. They are found in the Arctic tundra and boreal forests. Finland is home to a small population of woodland reindeer.
Several named Rangifer fossils in Eurasia and North America predate the evolution of modern tundra reindeer. Archaeologists distinguish “modern” tundra reindeer and barren-ground caribou from primitive forms — living and extinct — that did not have adaptations to extreme cold and to long-distance migration.

The mountain reindeer has several physiological adaptations to cope with different environmental temperatures. Reindeer have hemoglobin that allows for high oxygen unloading even at very cold temperatures. [1] This is essential because reindeer limbs are often kept much colder than core body temperature, a phenomenon known as regional ...
The boreal woodland caribou (Rangifer tarandus caribou; but subject to a recent taxonomic revision.See Reindeer: Taxonomy), also known as Eastern woodland caribou, boreal forest caribou and forest-dwelling caribou, is a North American subspecies of reindeer (or caribou in North America) found primarily in Canada with small populations in the United States.
Reindeer live in the far northern regions of Europe, North America, and Asia.They enjoy colder climates like tundra and boreal forests. We can find them in northern countries, which include:
