insectivore (ĭnsĕk`təvōr'), term broadly given to any insect-eating animal or plant. More specifically, the term refers to mammals of the order Insectivora (see Chordata Chordata , phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate

Insectivores are small animals, ranging from 2 to 16 in. (5–40 cm) in length; they are generally quite active, and most of them are nocturnal. They feed on a variety of small animals, particularly worms and insects. Members of this group are thought to be closely related to the earliest placental mammals. The tenrecs have certain anatomical features in common with the more primitive pouched, or marsupial, mammals. The other groups of placental mammals, including the primates, the order to which man belongs, are thought to have evolved as radiations from a primitive insectivore stock. The tree-shrews were formerly classified as insectivores, but are now usually classified as primates; they represent a transitional form between the two groups. Primitive insectivores may have been arboreal, e.g., the tree shrew, but modern forms are ground or even underground dwellers; the mole is highly specialized for subterranean life. Insectivores are found in the Old and New Worlds from subarctic regions to the tropics, but there are none in Australia, New Guinea, New Zealand, or most of South America. insectivoreAny 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. insectivore 1. any placental mammal of the order Insectivora, being typically small, with simple teeth, and feeding on invertebrates. The group includes shrews, moles, and hedgehogs 2. any animal or plant that derives nourishment from insects How to thank TFD for its existence?
