Hedgehogs and moonrats are quite primitive, and bear a certain resemblance in appearance and habits to the earliest mammals. Unlike those early mammals, they bear live young instead of laying eggs. Hedgehogs have spines, but moonrats (also known as gymnures) do not. They are all omnivores.
Scientific name: Erinaceidae
