Explanation:

The shrew (family Soricidae) is a small mole-like mammal classified in the order Eulipotyphla. True shrews are not to be confused with treeshrews, otter shrews, elephant shrews, or the West Indies shrews, which belong to different families or orders.

Although its external appearance is generally that of a long-nosed mouse, a shrew is not a rodent, as mice are. It is, in fact, a much closer relative of hedgehogs and moles, and shrews are related to rodents only to the extent that both belong to the Boreoeutheria magnorder – together with humans, monkeys, cats, dogs, horses, rhinos, cattle, pigs, whales, bats, and others. Shrews have sharp, spike-like teeth, not the familiar gnawing front incisor teeth of rodents.

Shrews are distributed almost worldwide; of the major tropical and temperate land masses, only New Guinea, Australia, and New Zealand have no native shrews; in South America shrews appeared only relatively recently, as a result of the Great American Interchange, and are present only in the northern Andes. In terms of species diversity, the shrew family is the fourth-most successful mammal family, being exceeded only by the muroid rodent families Muridae and Cricetidae and the bat family Vespertilionidae.
