mongoose Facts. Although they appear remarkably similar to weasels in form and lifestyle, mongooses are actually members of the superfamily feliforma, or cat-like carnivores, while weasels are in the superfamily caniforma or dog-like carnivores.
They are distinguishable from beavers by their smaller size and the characteristics of the tail and feet. Muskrats have a tail that is flattened vertically (the opposite of the beaver) and is longer and more rat-like. Their feet have skin folds between the toes but not the extensive webbing that beavers have.Muskrats are not as damaging as beavers because they do not block pipes and outfalls with sticks and mud.hey have sharp, predatory teeth. Otters are more vocal than beavers and muskrats, letting out the occasional yelp or bark. Otters also can be identified by the evidence they leave behind. Otters tend to enter and leave ponds in the same place, which over time creates a worn area known as an otter slide.
