Thanks
to a unique respiratory system, the beaver is able
to remain underwater for periods of up to 20-minutes
at a time. The tail of the beaver is unusually broad
and covered in scales. The beaver uses his tail
like a rudder to maneuver through water. It is also
used as a communication tool. It is common for the
beaver to slap water with his tail to warn others
of impending danger. Beavers exist on a diet of
bark, twigs and buds of trees. During spring and
summer months, beavers also consume corn and other
crops, including water plants. As Autumn nears,
the beaver begins to harvest trees, shrubs and some
greens, storing food for the winter inside their
den. Natural enemies of the beaver include bears,
wolves, fishers, otters and the lynx. The average
lifespan of the beaver is 12-20 years.
