The Pygmy Shrew is one of the smallest mammals in the world, with adults sometimes weighing less than a dime. Despite its tiny size, it must eat 1.25 times its body weight daily and hunts continuously with barely a pause for rest. Its heart beats up to 1,200 times per minute when active—among the fastest heart rates of any mammal.
