Which of These Animals is Tougher?

The lynx and wolverine are both formidable, elusive predators.

The lynx and the wolverine are both formidable predators known for their elusive nature. 

Roaming the remote northern forests of North America, Europe, and Asia, lynx are skilled hunters that make use of great hearing (the tufts on their ears are a hearing aid) and eyesight strong enough to spot a mouse 250 feet (75 meters) away. Canada lynx eat mice, squirrels, and birds, but prefer the snowshoe hare.

Bigger Eurasian lynx, such as the animal pictured above, hunt a wider range of animals, from small mammals to deer.

Native to North America, the wolverine is a powerful animal that resembles a small bear but is actually the largest member of the weasel family. They are tenacious predators with a taste for meat. (See "Searching for Wolverines by Running Through the Woods.")

Wolverines easily dispatch smaller prey, such as rabbits and rodents, but may even attack animals many times their size, such as caribou, if the prey appears to be weak or injured.

These predators have also appeared in Photo Ark—Nat Geo’s project with photographer Joel Sartore to document the world's 12,000 captive species. (Take the quiz: "What Animal Is Most Like You?")

So far, he's visited 40 countries and photographed more than 6,000 species with the studio lighting and black-and-white backgrounds that give the collection its iconic look.
