Where the species is not unique to Alaska, this article gives information about the habits and distribution that are characteristic of animals occurring in the state.
Alaska shrews have not been studied as much as most of its animals, so many particulars of their distribution, breeding cycles, and population remain unknown.
All of Alaska's shrew species look alike to lay observers, but experts differentiate them based on their ranges and skull structure.
Shrews live throughout the state, even on isolated islands, in habitats from temperate rain forests of the Southeast to Arctic tundra.
Their predators in Alaska include weasels, marten, fox, domestic cats, other shrews, and owls.
