Most vole species have rootless molar teeth which fold in to a series of triangles. Unlike most rodents, voles' molars, as well as their incisors, grow continuously.
They range in size from three to seven inches in length.
Voles live in a variety of environments. The North American meadow vole lives in networks of above-ground "runways" in grassy areas, as well as underground burrows. California's red vole lives in the tree tops.
Diet consists mainly of various green vegetation, such as grasses and clover, but also of tubers, conifer needles, bark, and insects, depending on species.
Most carnivores in the vole's range, from owls and hawks to coyotes, foxes, weasels, and cats, will eat voles.
Most voles do not live past 12 months.
