The Kamchatka shrew (Sorex camtschatica) is a species of mammal in the family Soricidae. It is endemic to Russia.


The species was first described in 1972. Before that it was considered a subspecies of cinereus shrew (Sorex cinereus).[2]


Kamchatka shrew inhabits riparian scrubs in North-Eastern Siberia, in the upper reaches of the river Omolon (its tributary Kegan), and in Kamchatka (Kambalny Bay, Lake Azhabachye, neighborhood of Milkovo).[3]


The body length reaches 66 mm (2.6 in), with an average of 57 mm (2.2 in). The tail is about 79% of the body length and can be 54 mm (2.1 in) long. The average weight of an adult is 5 g (0.18 oz).[4] The back is ashy-gray, sides are lighter, with brown tones. The belly is light gray.[5] This species is characterized by the highly elongated rear feet with well-defined bristle brush hair.[2]

Life events[edit]

Biology of the species is poorly understood. The breeding season lasts from April to September. Females annually produce up to three litters with 5.1 cubs per liter on average.[5]
