Watch Those Antlers Grow

A deer's antlers are the fastest growing living tissue on Earth.

The antlers grow between the Spring months and the Fall months.  While growing, the antlers are covered with a soft tissue known as velvet, which contains a sensitive network of nerves and blood vessels.   In the Fall, the velvet is shed and the antlers harden.  The antlers are then shed in the winter.
