Any member of the mammalian order (Insectivora) that includes the hedgehogs, moles, and sometimes shrews (some of which are considered primates by some authorities), or, more generally, any animal that eats mainly insects. The mammalian insectivores are generally small, active, and nocturnal. They are found in most parts of the world except Antarctica, Australia, and South America. Most species are solitary (except during the breeding season) and short-lived.
