Most characteristic feature is a flattened paddle like tail
The beaver is a true Tennessee water conservationist which has caused problems in some of the states bottomland areas.
It builds water tight dams of sticks and mud across streams and cone shape houses known as lodges.
Beaver dams slow the flow of water in fast streams, changing the composition of life in the stream. Increased siltation and flooding in low-lying areas are just a few of the problems associated with beaver dams.
Beaver dams can , however, prevent erosion and purify the water in a stream.
Beavers possess castor glands which is located at the base of the tail. These glands are used to mark an animals territory.
Beaver families are very territorial and will defend its territory from encroaching beavers.
Beavers are primarily nocturnal, although they may sometimes be seen during the day.
The beavers ears are short, round and dark brown in color. The ears are closable when the animal is in the water. The beaver possesses closable nostrils and a transparent eye membrane. These characteristics aid in the beavers aquatic existence. When walking on dry land a beavers rear end is higher than his front end, this is due to the fact that the beavers hind are longer than his front legs. The beavers upper incisors are bright orange in color and continue to grow throughout the beavers life. The beavers flat, scaly tail serves as a rudder when the beaver is swimming and as a warning device when slapped on the water. The beavers tail is also used for support when standing on land or dragging logs.
