The beaver is the second-largest rodent in the world and can weigh up to 80 pounds, though the average weight is 40-50 pounds. They are aquatic rodents and have large, flat, scaled tails that are very distinctive. Beavers live in family groups and are known for being habitat engineers. They build dams to block flowing water to form wetlands and ponds and live in large houses they construct. They give birth to 2-5 kits in May or June and young disperse after 2 years with their parents.
