Beaver Fact of the Week: Beavers are Big

Beaver are rodents. When I think of rodents, I tend to think of smallish mammals. I think just about everyone knows that beavers are bigger than field mice, but how big are they exactly?

Answer: Beavers are huge! North American beaver, Castor canadensis, can grow up to 3.5 feet long nose to tail, and weigh up to 60 pounds! Yep, 60 pounds. That’s 27 kilograms. That’s as much as an adult medium sized dog, like a Collie or female German Shepard. Eurasian beaver, Castor fiber, tend to be around 40 lbs, although the Smithsonian Institute reports a record weight of 88lbs. Let that sink in for a moment. The biggest beaver weighed about as much the average 11 year old girl.

Alright, this beaver statue may be a bit of an exaggeration. But adult beavers really are surprisingly large.
