Birch mice (genus Sicista) are small jumping rodents that resemble mice with long, ... All variants possess a long tail of 65 to 110 mm (2.6 to 4.3 in) of length and ...
A closeup of a rat tail. The characteristic long tail of most rodents is a feature that has been extensively studied in various rat species models, which suggest three primary functions of this structure: thermoregulation, [13] minor proprioception, and a nocifensive-mediated degloving response.

Rodents are animals that gnaw with two continuously growing incisors. Forty percent of mammal species are rodents, and they inhabit every continent except Antarctica. This list contains circa 2,700 species in 518 genera in the order Rodentia. [1]
The woodland jumping mouse occurs throughout northeastern North America. [6]Populations are most dense in cool, moist boreal woodlands of spruce-fir and hemlock-hardwoods where streams flow from woods to meadows with bankside touch-me-nots and in situations where meadow and forest intermix and water and thick ground cover are available.
Most rodents are small animals with robust bodies, short limbs, and long tails. They use their sharp incisors to gnaw food, excavate burrows, and defend themselves. Most eat seeds or other plant material, but some have more varied diets.
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). It is the largest species in the subfamily Arvicolinae, which includes 142 other species of rodents, mostly voles and ...
The tail is squirrel-like - bushy, and flattened from base to tip. [3] [5] These woodrats are good climbers and have sharp claws. They use their long tails for balance while climbing and jumping, [3] and for added warmth. [6] These rodents are sexually dimorphic, with the average male about 50% larger than the average female. Its adult length ...
Voles are small rodents that grow to 8–23 cm (3–9 in), depending on the species. Females can have five to ten litters per year, though with an average lifespan of three months and requiring one month to adulthood, two litters is the norm. [1] Gestation lasts for three weeks and the young voles reach sexual maturity in a month.
