A beaver (海狐) has a large flat tail,which acts as a support when they sit or stand,a rudder (舵) when they swim,and a warning sign to others when danger is coming.Beavers can weigh as much as 60 pounds.The female is normally as large as or larger than the male.They have dark brown fur that is waterproof (防水的).Their eyesight is poor but other senses (hearing,smell and touch) are great.Beavers have large front teeth that stick out from their mouth.They never stop growing so beavers must bite on wood often to keep them short.Their noses have valves that stop water getting in their mouth when they chew on underwater wood.They can stay underwater for about 15 minutes at a time.Beavers only work at night and they are amazing builders.Much of their building material comes from trees.In one night,they can bite down many trees.First,the beaver will build a dam.This creates a pond for them to place their lodge (巢穴).The still,deep water protects them from enemies,including bears and wolves.They also make their entrances underwater to keep enemies from entering.Their dams and lodges can last for many years.They are well-constructed and require much effort to tear down.The male and female will produce many litters.Mothers often raise teenagers and newborns.In fact,the teen beavers will help with the younger beavers.A mother beaver will have two to four babies at a time.The young beavers will move out when they are about two years old.They will find mates and build their own lodges in another area.
