Adult muskrats typically grow to be 40–70 cm (16–28 in) long, with about half of that length attributed to their tail, and weigh between 0.6–2 kg (1+1⁄4–4+1⁄2 lb).
Understanding Muskrat Dimensions
Muskrats are medium-sized semi-aquatic rodents, known for their compact bodies and long, scaly tails. Their size makes them a prominent inhabitant of wetlands across North America.
Body Length
When considering a muskrat's total length, it's important to note the significant contribution of its tail. An adult muskrat's body, from nose to the base of its tail, is relatively smaller than its total length suggests.
- Total Length: 40–70 cm (16–28 in)
- Tail Length: Approximately half of the total length
Weight
Muskrats are surprisingly robust for their length. Their dense fur and compact build contribute to their overall weight, which can vary depending on factors like age, sex, and food availability.
- Weight Range: 0.6–2 kg (1+1⁄4–4+1⁄2 lb)
Muskrat Size at a Glance
For a quick reference, here's a summary of an adult muskrat's typical dimensions:
Characteristic | Metric Measurement | Imperial Measurement |
---|---|---|
Total Length | 40–70 cm | 16–28 in |
Weight | 0.6–2 kg | 1+1⁄4–4+1⁄2 lb |
Comparing Muskrats to Other Rodents
While only slightly longer than a brown rat (Rattus norvegicus), an adult muskrat is considerably heavier. It can weigh roughly four times as much as a brown rat, highlighting its more substantial build and different ecological niche. This larger size allows muskrats to better withstand colder aquatic environments and deter some predators.
