Elephants have 100 times as many cells as humans. But they seldom get cancer. This is surprising, because cancer is a result of cell division gone wrong, and the more cells an organism has, the higher the chances that some will mutate into tumors. Also, because elephants live so long - between 60 and 70 years - their cells have more opportunities to mutate. The counterintuitive observation that cancer risk does not always correlate with a species' size or longevity is known as Peto's Paradox, named after British epidemiologist Richard Peto, who first noted the phenomenon in 1977. It turns out that cancer does not strike all species equally: Some animals have evolved powerful strategies to keep the disease at bay, while others are particularly vulnerable.

Here are some of the possible explanations for the weirder traits of man's best friend... Why does my dog lick me?
