Battle of the Alphas

Madagascar is home to strange animals not found anywhere else on Earth. When these animals fight for supremacy, their battles are just as strange -- from weird neck-wrestling weevils to ring tailed lemur mums that go into battle with baby on board.

Australia is home to an eclectic array of creatures, and the ways to succeed as an alpha are just as diverse. The beach turns into a dueling ground, and the outback becomes a boxing ring, as animals face off with their own kind.

The African savanna is an epic landscape, and whether it's head-bashing hippos, hormone-crazed elephants or dueling lions, battles that rage on the savanna are just as epic.

Welcome to India, a land of exotic animals and exotic warfare. Monkeys stir things up, Indian antelopes wage war on the open plains and peacocks sharpen their knives.

Massive elephant seals go nose to nose to win the title of beachmaster, and giant petrels earn the nickname, murderous garbage men. Meanwhile, a female humpback goes to extremes to protect her calf from amorous males.

Canada, where summer is short and time is tight, any time is the right time to fight. The mighty North provides the setting for bison, bald eagles, and polar bears to wage some of the most heavy-duty fighting in the animal kingdom.
