Northern Short-Tailed Shrew

Blarina brevicauda




First Noted by Expedition
April 7, 1805; shipped from Fort Mandan to Washington, D.C.
 

Description
The largest shrew in North America. Solid gray. Length: 3.85 in (9.612.7 cm); tail: 0.81 in (22.5 cm). Weight: 0.05 oz (1429 g).
 

Habitat
In the north, a variety of habitats; in warmer, drier parts of range, more confined to woods and wet areas.
 

Range
Southeastern Canada and northeastern U.S. south to Nebraska, Missouri, Kentucky, and in mountains to Alabama. Isolated populations in northeastern North Carolina and west-central Florida.
 

Note
Shrews of the genus Blarina are unique among mammals in producing poison in their salivary glands. The saliva is not dangerous to humans, but a bite may swell and be painful for days. The poison is apparently used to paralyze prey, such as snails and earthworms, which can then be stored for future use.
