10 Fun Facts about Beavers
The numerous ways a beaver shapes its environments for survival are awe-inspiring. Here are some fun facts about beavers that you might not have known about.
1. Beavers have giant ancestors.
Beavers used to be giants back in the Ice Age. Named “Castoroides,” they looked similar to the modern beavers but only much bigger. They grew up to 8 feet long and weighed a staggering 200 pounds.
2. It’s not a diet of Cheetos, honestly!
A beaver’s front teeth are orange in color. They require strong teeth to gnaw through trucks of trees, and their tooth enamel, fortunately, contains iron. This makes their teeth extremely strong, sharp, and indeed orange.
3. Beaver tails are highly adaptable.
The tail of a beaver is helpful in both land and water. Their leathery, oversized tail can grow as long as 15 inches, and it can be used for swimming (uses its tail as a rudder) or as a warning to other beavers that a predator is present (through slapping it against the water).
4. However, they use more than just their tails to swim around.
To help them navigate through the water, beavers make use of a wide variety of adaptations (necessary for the mammal to live a semi-aquatic life). For example, the valves in their ears and nose shut when they enter to swim to keep out the water. In addition, their lips closed behind their big front teeth, which enables the beaver to transport food and materials for building without drowning.
5. Hold your breath!
Beavers can remain underwater for 15 minutes without breathing.
6. No need for goggles here!
To help them see underwater, beavers are equipped with a third transparent eyelid.
7. Beaver dams are incredible feats of engineering.
The wilderness of northern Alberta is home to the world’s largest beaver dam (stretching 850 meters). It was discovered in 2007 via a satellite image, and scientists believe that numerous generations of beavers have been working on the dam, and it goes back as far as the 1970s. An explorer named Rob Mark was the first person to reach the dam.
8. Sky beavers? Anything’s possible…
Although hard to wrap your head around, beavers have once traveled via a parachute. As the people of Western Idaho began to clash with the beaver population back in 1948, the Idaho Department of Fish and Game were determined to move these threatened beavers to a nearby area that was more protected. They devised a plan, including using World War II surplus parachutes to drop boxes of beavers down from planes. Out of the 76 beavers that made the skydive, every beaver except one survived the fall.
9. They’ll cost you!
Property damage caused by beavers in the U.S. is estimated to be around $100 million every year!
10. Keeping dentists at work!
The front teeth never stop growing, as with all rodents.
