Crouching tiger

The tiger is a 'concealment and ambush hunter', carefully stalking prey, circling in as closely as possible, and then suddenly charging the target from behind.

When hunting, this cat circles around to approach downwind from its quarry and may take twenty minutes to creep over ground which would be covered in under one minute at a normal walk.

At a distance of approximately 50 feet the tiger will sometimes pause, seemingly hopeful that its target may inadvertently move closer and so lessen that critical attack distance. The cat will raise and lower its head, judging the distance and angle, before finally raising its body and charging.

A tiger will not normally charge at prey until it has made some abrupt movement, but will endeavour to get in closer, so increasing the chances of a successful kill. Nor do charging tigers roar, or make any sound during an attack.

For the prey, death comes silently.

Yep. That grasshoper didn't know what hit him.
