Synonym discussion

Sense: noun/1

For the animal sense, beaver is much more specific than rodent. A rodent is any animal in a large group with front teeth that keep growing, so mice and squirrels are rodents too. Muskrat is closer because it also lives around water, but a muskrat is smaller and is not known for building large dams. Otter often appears in similar river scenes, yet an otter is not a rodent and is better known for catching fish and swimming. Use beaver when you mean the flat-tailed animal that cuts trees and blocks rivers with wood and mud. For example: We saw a beaver carrying branches. The pond was full of muskrats, not beavers.
