The Spiny Hedgehog

  • Jessica H. Lewis


The order Insectivora consists of fewer than 400 species of insect-eating mammals: moles, shrews, and hedgehogs. Hedgehogs are large rat-sized animals weighing 0.4–1.1 kg. They live in the temperate climates of Europe and Asia. Their backs and sides are covered with a protective coat consisting of long hairs mixed with sharp striped spines. When the animal is frightened, circular muscles under the coat contract, erecting the spines every-which-way and rolling the animal into a protected ball.
