From a rhinoceros relative the size of four elephants to a kin of the shrew small enough to fit on the end of a pencil, the world of mammals -- both extinct and surviving to this day -- is full of extremes, and oddities. A whale with legs and a "bear" that can wrap itself up in its own tail to sleep are among the creatures featured in "Extreme Mammals: The Biggest, Smallest, and Most Amazing Mammals of All Time," an exhibit on display April 3 through September 12 under the green roof of San Francisco's new California Academy of Sciences building after a stint at the American Museum of Natural History (AMNH) in New York City. Some are funny, some ferocious, but all of them will wow you.
