18 animals of the tundra and their characteristics

Some of the tundra animals most representative They are the arctic hare, the caribou or reindeer, the harlequin duck, the snowy partridge, the polar bear or the gray bear. In order to inhabit areas with temperatures as low as the tundra, the animals that inhabit these places have had to adapt.

The tundra is a biome characterized by frozen subsoil, little or no tree vegetation, and soils covered with mosses and lichens. In this way, the species with the easiest to live under these climatic conditions are those that have survived. In the tundra there is not as much biodiversity as in the jungles and tropical forests.
