From head to toe, every part of the beaver's body is designed to help the animal perform a job or survive in its surroundings. Can you match the body part with its function?
1. This clear membrane closes whenever the beaver enters the water. It protects the eye and lets the animal see better underwater.
2. These are webbed to help the beaver swim faster. The first two toes have a double claw that the animal uses to comb its fur.
3. This part serves as an alarm, a rudder when the beaver is swimming and a counterbalance when it is felling a tree. It also helps to control the animal's temperature and stores fat, a source of energy for the beaver when food is scarce.
4. The beaver has two kinds of this. The longer ones give the animal its color and keep the animal warm in cold weather. The shorter ones are so dense that the beaver's skin does not get wet, even when it is underwater.
5. The front two pairs of these are constantly growing and are used to bring down trees for the beavers' dams, lodges and food. The ones in the back are used to grind trees into digestible food. These are so sharp that Native Americans once used them to make knives.
6. These protect the beaver's ears and nose by shutting when the animal is underwater.
7. These help the beaver dig. One of the outside fingers acts like a thumb, which allows the animal to grasp objects
8. Located between the two pairs of front teeth and the back molars, these shut when the animal is underwater, which lets a beaver push logs with its front teeth without water entering its mouth, preventing the animal from drowning.
