A deadly venom is obtained from the skin glands of the arrow poison frog of South America.

It is still being used by the Indian hunters to kill small animals and birds.

The frogs are roasted over a fire and the venom exuding from their skins

is collected and used to coat the tips of the arrows of the hunters.

The frogs produce the venom to protect themselves

from the other predators such as lizards and snakes.

Their brightly colored skins and the brilliant mosaics of

red, yellow, orange and blue serve to remind the predators

that they are too dangerous to be included in their menu.
