Shrew
In general, shrews live in and on the ground. They search for seeds, insects, nuts, and worms. Some climb trees, some live underground, some live under snow, and some hunt in water. They have small eyes, and generally poor vision, but have excellent senses of hearing and smell. They are very active animals, with big appetites. Shrews have an unusually high metabolic rate. Shrews usually eat 80–90% of their own body weight in food daily.
