| name = Ussuri shrew[1] | status = DD | status_system = IUCN3.1 | status_ref = [2] | genus = Sorex | species = mirabilis | authority = Ognev, 1937 | range_map = Ussuri Shrew area.png | range_map_caption = Ussuri Shrew range }} The Ussuri shrew (Sorex mirabilis), also known as the giant shrew,[3] is a species of shrew found in Northeast Asia. An adult Ussuri shrew has a total length including the tail of {{convert|137|to|170|mm|in|1|abbr=on}}. It is found in valleys and on the forested slopes of mountains in the Korean Peninsula, northeastern China, and the Russian Far East. It is rarely observed, and its ecology is largely unknown.[3] DescriptionThis is the largest shrew in the genus Sorex and grows to a head-and-body length of {{convert|74|to|97|mm|in|1|abbr=on}} with a tail of {{convert|63|to|73|mm|in|1|abbr=on}}. The hind foot is {{convert|16|to|18|mm|in|1|abbr=on}} long and the weight is {{convert|11|to|14|g|oz|1|abbr=on}}. Both the dorsal pelage and the underparts are iron grey.[4] The large size, robust tail and various details of the dentition help to distinguish this shrew from other species.[5] Distribution and habitatThe Ussuri shrew is native to northeastern China, northeastern Korea and southeastern Russia. It inhabits both broadleaf and mixed coniferous/broadleaved forests in valleys and on hillsides, and is present on mountains in South Korea at altitudes of over {{convert|1500|m|ft|-3|abbr=on}}. It prefers moist locations and also occurs in marshes at higher altitudes.[2][5] EcologyThe Ussuri shrew is a terrestrial species and creates burrows. Although it also eats insects, other invertebrates and carrion, about 82% of its diet consists of earthworms, and because of their relatively low nutritional value, it needs to eat more than twice its bodyweight each day.[5][4] It is presumed to nest underground but its breeding habits are little known. There is normally one litter per year and by August, the young are sometimes caught in traps. A second litter may be born when circumstances permit, and the young become sexually mature at 11 months of age.[5][4] StatusThe International Union for Conservation of Nature does not have enough information on this species to rate its conservation status, and has listed it as being "data deficient". However, the Ussuri shrew has a wide range and, despite being a rarely seen and poorly known species, when more information becomes available, it may turn out to be of "least concern".[2] See also
