Description | Description:Beavers are brown or grey nocturnal animals which build dams in rivers, using sticks, leaves, and mud. They are great in the water, but slow on land, and will slap their flat tails on the water as a sign and warning of distress. | Description:Porcupines are the largest of all rodents,living in jungles of Africa, Europe, and Asia. They are coated with long poisonous spikes for defense. These spikes separate from the porcupine, painfully stick into the victim, and are difficult to remove. Porcupines are mostly grey and brown, but some are white in color. |
