Animalia > Chordata > Mammalia > Soricomorpha > Soricidae > Sorex > Sorex hoyiSorex hoyi (pygmy shrew; American Pygmy Shrew)Synonyms: Microsorex hoyi; Sorex thompsoni Language: French The American pygmy shrew (Sorex hoyi) is a small shrew found in Northern Alaska, Canada and the northern United States down through the Appalachian Mountains. It was first discovered in 1831 by naturalist William Cane in Georgian Bay, Parry Sound. This animal is found in northern coniferous and deciduous forests of North America. It is believed to be the second smallest mammal in the world, but has an extremely large appetite for its size. Due to its fast metabolism, it needs to eat constantly. It digs through moist soils and decaying leaf litter for food. |
