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.
The genus Sorex includes many of the common shrews of Eurasia and North America, and contains at least 142 known species and subspecies. Members of this genus, known as long-tailed shrews, are the only members of the tribe Soricini of the subfamily Soricinae (red-toothed shrews). They have 32 teeth.
The southern short-tailed shrew is the smallest shrew in its genus, measuring 7 to 10 cm (2.8 to 3.9 in) in total length, and weighing less than 14 g (0.49 oz).It has a comparatively heavy body, with short limbs and a thick neck, a long, pointed snout and ears that are nearly concealed by its soft, dense fur.
Elliot's short-tailed shrew was originally described as a subspecies of Blarina brevicauda, and was only identified as a separate species in 1981. Genetic analysis to determine its precise relationship to other members of the genus has been ambiguous, with some studies placing it as the closest relative to the southern short-tailed shrew, [ 6 ...
