Animals have many important attributes to humans. First, this “naked” shrew is immune to cancer. The lifespan of this animal is up to 28 years – this is truly incredible for mammals. Plus, it hasn’t aged much in its 28 years of age. Young, strong, and resilient all day long are the top attributes of this wonderful animal. This type of shrew is often used by humans to research the preparation of cancer drugs and research on aging. Not only is it a strange animal with a slightly “horror” appearance, the “naked” shrew is also an animal that plays an important role for humans.
