noun
muskrat
MUSK-rat/ˈmʌskræt/
A semiaquatic North American rodent with a musky odor.
The muskrat rests beside the marsh with its long, flattened tail visible.

Etymology
The Algonquian name, probably Powhatan, referred to the animal’s reddish coloring. Association with the familiar words musk and rat reshaped that name into one suggestive of its smell and rodent identity.
In context
It's not a fish, not a duck. It's one of North America's most underrated ecological engineers, the muskrat.
