About half of all mammal species are rodents!
There are many different kinds, including squirrels, mice, and porcupines.
Rodents include jumpers like jerboas,
swimmers like muskrats,
and diggers like prairie dogs and groundhogs.
They can have bushy tails, naked tails, or armored tails.
The most bizarre rodent may be the naked mole rat,
with its tiny eyes, naked body, and projecting incisor teeth.
