List of rodents

Beavers are a small, brown animal related to the squirrel. They are found in America and Europe. They spend their time in and around water, and are excellent swimmers. Beavers are best known for their ability to build dams. They cut down trees with their sharp teeth and drag the logs to where they need them, and stack them up to make a dam. They end up with their own ponds that they tend to, which protects their den. Beavers eat waterlilys.

Flying squirrels are a variety of squirrel that has a flap of skin joining its front and back legs. Flying squirrels can spread out this flap like a parachute to glide between trees.

Guinea pigs, also called the cavy, are a small rodent originally from South America. They were first domesticated as a food source, but today guinea pigs are kept as pets. They have a quiet nature and don't mind being handled.

Lemmings are small rodents closely related to voles. They eat mainly leaves new shoots and grasses. Lemmings will sometimes migrate in large numbers, not stopping even if a cliff gets in the way, which has lead to many myths about their behaviour.

Porcupines are a large rodent related to the beaver. They are spiny like hedgehogs and echidnas but are not related to either of them. Porcupines come in many shapes and sizes, but all have sharp quills. Porcupines can lose their quills, so if something bites a porcupine they get a mouthful of spikes.
