African crested porcupine

Porcupines are nocturnal animals, sleeping in the day and foraging for food during the night. When alarmed or under threat, porcupines have a great defence mechanism, their quills. These quills are so dangerous that they are one of the biggest killer of lions in Africa. Their teeth never stop growing, so they gnaw on wood to help keep them trimmed. Young lions think porcupines are an easy target, but when approached, the porcupine will run backwards and spike the predator causing fatal injuries to the predators head.
