The European mole (''Talpa europaea'') is a mammal of the order Eulipotyphla. It is also known as the common mole and the northern mole.〔(''Talpa europaea'' ), nomen.at〕 This mole lives in an underground tunnel system, which it constantly extends. It uses these tunnels to hunt its prey. Under normal conditions the displaced earth is pushed to the surface, resulting in the characteristic molehills. It feeds mainly on earthworms, but also on insects, centipedes and even mice and shrews. Its saliva contains toxins which paralyze earthworms in particular. It has a cylindrical body and is around long. Females are typically smaller than males. The eyes are small and hidden behind fur, while the ears are just small ridges in the skin. The fur is usually dark grey, but the actual range of colors is larger, as due to the subterranean habits there is no disadvantage in having off-colored fur. European moles with white, light grey, tan, taupe, and black fur have all been reported. ==Habitat== While moles are typically found in tunnel systems, the European mole is not exclusively an underground dweller. In the spring and early summer when the young moles leave their mothers' burrows they must find new territory. This forces them to leave their burrow and they can either make new tunnel systems or enter existing systems. In the summer time, however, they will likely burrow much more superficially. The superficial burrowing could be due in part to the soil that is much harder, which makes burrowing a greater challenge. ''T. europaea'' have also been found to spend a lot of time at the sides of drainage lines and streams but do not inhabit flooded or dry soils. However, dry areas do become important when their normal habitats become flooded. Factors such as the type of soil, vegetation present, and altitude have no effect on the areas that moles choose to inhabit. The one factor that does greatly influence the mole population in a specific area is the abundance of earthworms. One would expect for the earthworm population to decrease as the moles feed, however no research has shown this to be true. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「European mole」の詳細全文を読む スポンサード リンク
