Their eyes are tiny and ears are hidden in the fur. Their fur is usually brown or grayish darker on the back than on the belly. They are very shy animals, darting into the under growth or down a burrow at the slightest sound.
Shrews feed manily on insects, worms, and other small animals.
Their teeth are sharp and pointed. Shrews are extremely nervous animal. Sudden loud sounds can literatly frighten the to death. When frightened,their heart may beat up to 1,200 times a minute. My wife certainly doesn't see anything funny about this.
