Answer: Giraffes

When we think of plant eaters, we generally don’t think of creatures that actively stalk their prey, but in the case of giraffes there is distinct methodology to how the giraffe approaches and eats its food.

The acacia tree, one of the giraffe’s favorite plants to devour, will release tannins when it is distressed, which make the flavor of the leaves bitter. Other acacia trees in the area will detect these tannins and will in turn release their own tannins. To avoid having an entire meal of bitter leaves, giraffes have learned to graze against the wind so that each new acacia tree they visit is unaware that it is dinner until it is too late.
