Trivia: Which semi-aquatic rodents are known for building dams?
The correct answer is Beavers
So why is this answer correct? : Beavers have adapted well to life in the water. Their webbed toes and flat, hairless tails are perfect for navigating through rivers and lakes in search of logs to build their dams. However, their greatest tool is their distinctive teeth, which are more orange than other rodents due to the iron in their enamel that makes them strong enough to chew wood.
