Hedgehogs are covered with sharp quills that aid in their protection. Many species of hedgehogs can roll into a ball, hiding all vulnerable areas of the body under the protective spines. Hedgehogs live under logs or in burrows that they dig. They eat a wide variety of foods, including invertebrates, reptiles, carrion, roots, and fruits. Hedgehogs are active only at night, and some species hibernate in the winter.nnSpecifications:nnSkull Length 4.3 cm (1.7 in.)nSkull Width 3.1 cm (1.2 in.)nSkull Height 2.4 cm (0.9 in.)
