Meet the animals who will steal, cheat and fight to get food, including kleptomaniac crabs, thieving macaques, con artist spiders, tricky tigers and cannibalistic lizards.

Some animals will do whatever it takes to survive. Cockatoos turn to vandalism, boxer crabs hold anemones hostage, sloths become filthy, puff adders have an ‘invisibility cloak’ to hide themselves, and chimps use violence to stay in power.

Getting ahead in the mating game requires some astonishing behavior –from promiscuous prairie dogs to manakin pick-up artists, kidnapping macaques and hyenas with a bad case of sibling rivalry.

Discover the ingenious strategies that nature’s biggest beasts employ to conquer their environments, from the Komodo dragon with a deadly bite to the tallest giraffe to the bird-eating Armored ground cricket. These are their epic survival stories.
