In isolated pockets of Siberia and India, they are the one hunter all animals, including humans, fear: Tigers.
Weighing as much as 600 pounds.
Bringing in a nasty set of canines and claws to every encounter.
Sprinting at 35 miles per hour.
But the biggest and most powerful cat on Earth misses far more often than it kills because it lacks one key quality: Stamina.
A large tiger has to get within pouncing distance of its target, otherwise it tires quickly and has to give up the chase.
To succeed the tiger depends on an unlikely weapon: its stripes.
Their color and pattern help this one blend into the grass.
On silent paws, a female moves undetected through the brush.
Stealing towards a band of monkeys.
Out of sight, she now has to wait for one to come close enough for a quick strike.
Success, but this monkey is little more than an appetizer or a snack to share with her young.
The cubs depend on the mother for up to three years.
Only half of them will survive that long, and when they do make it, staying fed can be a full time job.
