A general term for two species of mammals in the family Talidae of the order Insectivores. Aquatic moles that live in Europe. They resemble terrestrial moles, but have relatively long limbs and large, well-developed webbed hind feet. The webbed front feet are small. Their tails are long and have scent glands at their base that emit a musky odor. Their long, tube-like noses can be bent in all directions and act as a snorkel while swimming, and the nostrils at the tip close underwater. Their eyes are very small and they have no ears. They dig long tunnels into the riverbank to make their nests, and swim underwater to scavenge for food with their noses. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
