About more than half of the mammals on the earth are rodents. Rodents are small mammals that live all over the world, and there are many different kinds of them. All rodents have the same kind of jaw. Their teeth are used for grinding and gnawing food. If a rodent does not gnaw or grind its teeth, they will grow until the rodent isn’t able to eat anymore.
One small mouse-like rodent is a shrew. Shrews are very sensitive and shy. Their hearts beat about 1,200 times per minute—for comparison a human heart only beats around 80 times per minute. They are so sensitive that they can die of the shock by hard touch or loudness. Another type of rodent is the hedgehog. Hedgehogs rest during the day, and find food at night, eating food such as insects and frogs.
A different kind of rodent is a tenrec. Tenrecs are typically big-headed rodents, with pointy faces. They are found in The Comoros Islands and Madagascar. They have big wide mouths. Finally, there are moles. A mole mostly spends life in the darkness. They make tunnels and burrows to live in. They find food in their homes, such as earthworms and other invertebrates.
There are lots of interesting facts about rodents, what they eat, and where they live. Rodents love to eat and they live in many different places.
