The round-tailed muskrat (N. alleni) is only found in Florida and adjacent Georgia, just outside of the range of O. zibethicus. Some authorities place both genera in different tribes (Ondatrini for Ondatra , Neofibrini for Neofiber ), but the American Society of Mammalogists places both in Ondatrini, and some molecular evidence supports a close ...

They build nests to protect themselves from the cold and predators, often burrowed into the bank with an underwater entrance. Muskrats feed mostly on cattail and other aquatic vegetation but also eat small animals. Ondatra zibethicus is the only extant species in the genus Ondatra; its closest relative is the round-tailed muskrat (Neofiber alleni).

The most convenient distinguishing feature of the Arvicolinae is the nature of their molar teeth, which have prismatic cusps in the shape of alternating triangles. These molars are an adaptation to a herbivorous diet in which the major food plants include a large proportion of abrasive materials such as phytoliths; the teeth get worn down by abrasion throughout the adult life of the animal and ...
