The Gansu shrew is known from only three specimens. Its size has not been recorded. Shrews in the genus Sorex vary in size from about 50 - 100 mm (2 - 4"). They usually eat insects, worms and other small invertebrates. They can be active by day or night and do not become seasonally inactive. Shrews in the genus Sorex are generally solitary and highly aggressive towards each other. They have periods of deep sleep, but during their waking hours they are extremely active.
The Gansu shrew is known only from three specimens found in Gansu Province, China. It is restricted to relatively small patches of suitable habitat that are declining because of human encroachment.
*** Shrews in the genus Sorex are also known as "long-tailed shrews." The 68 species in this genus can be found in most of the temperate and arctic regions of the Northern Hemisphere.
*** Almost nothing is known about the status of the Gansu shrew (Stone 1995).

The Gansu shrew is known only from three specimens found in Gansu Province, China.
The Gansu shrew is restricted to relatively small patches of suitable habitat that are declining because of human encroachment (Nowak 1999).
Shrews in the genus Sorex vary in size (head and body length: 46 - 100 mm (1.8 - 4")) and weight (2.1 - 18 g (0.08 - 0.6 oz)).
Females usually breed first in the Spring of their second year.
Gestation in the genus Sorex is thought to range from 18 - 26 days (Nowak 1999).
Usually 1 - 2 years.
Shrews in the genus Sorex usually eat insects, worms and other small invertebrates.
Shrews in the genus Sorex can be active by day or night and do not become seasonally inactive. They have periods of deep sleep, but during their waking hours they are extremely active. The young sometimes travel by caravaning. (Nowak 1999)
