The
lemming is a small rodent living in the artic tundra. It is
herbivorous and feeds on green plants. These little animals
migrate south for the winters in amazing numbers.
Animals are
adapted to handle long, cold winters and to breed and raise young
quickly in the summer. Animals, such as mammals and birds, also
have additional insulation from fat which allows them to keep
warm.
Many animals
hibernate during the winter because food is not easily available.
Another alternative for may animals is to migrate south in the
winter, like birds do.
Reptiles and
amphibians are few or absent because of the extremely cold
temperatures.
Because of
constant immigration and emigration, the population continually
changes.
