The northern short-tailed shrew (Blarina brevicauda) is the largest shrew in the genus Blarina, [3] and occurs in the northeastern region of North America. [4] It is a semifossorial, highly active, and voracious insectivore and is present in a variety of habitats like broadleaved and pine forests among shrubs and hedges as well as grassy river banks.

The shrew subfamily Soricinae consists of thirteen genera.The majority of the species are contained within Cryptotis, with 41 species, and Sorex, with 76 species.The remaining shrews are split between Chodsigoa with eight species; Chimarrogale with six; Anourosorex, Episoriculus, Neomys, and Notiosorex with four species each; Blarina and Blarinella with three species each, and Megasorex ...
All shrews are tiny, most no larger than a mouse. The largest species is the Asian house shrew (Suncus murinus) of tropical Asia, which is about 15 cm (6 in) long and weighs around 100 g (3 + 1 ⁄ 2 oz) [2] The Etruscan shrew (Suncus etruscus), at about 3.5 cm (1 + 3 ⁄ 8 in) and 1.8 grams (28 grains), is the smallest known living terrestrial mammal.
More recently, the venom has been found to be related to that of the northern short-tailed shrew and it is mostly composed of kallikreins KLK1, serine proteases that prevent blood clotting, cause hypotension and ultimately end up being fatal to the prey.

The North American least shrew will also sometimes live inside beehives and eat all the larvae. It will often share its food with other shrews. It eats more than its body weight each day and is known to store food. [4] [7] The North American least shrew makes its home in burrows or shallow runways under flat stones or fallen logs.
The marsh shrew typically has a longer snout than that of the American water shrew, which is more streamlined when viewed from the side. [4] The marsh shrew's skull is relatively large, [3] and its condylobasal skull length is usually greater than 19.3 mm (0.76 in). [4] There is a distinctive, downward-sloping curve along the snout (rostrum). [3]
Notiosorex shrews have a fossil history that extends to the Miocene (i.e., mid-Hemphillian). The geographic distribution of the genus has always been in the southwestern United States and northern Mexico.
