Ergonomically designed to fit your hand and take the stress out of mousing. Traditional mouse designs force you to grip the mouse between your thumb and little finger. This strains the more delicate muscles in your hand and wrist. The Whale is designed to relax your hand. This allows the larger, stronger muscles in your arm to handle the stress of repetitive movement.
