Hunters in many areas of Latin America used a quiver and darts, in conjunction with a blowgun, to hunt small animals and birds for food. Originally, small ceramic pellets were used in the blowguns, but in later times the pellets were replaced with darts which could travel longer distances. The tips of the darts were wrapped in a natural fibre such as cotton or wool, and then dipped in poison. The poison would slow the animals down or even kill them outright. In Colombia, the most common type of dart poison was made from the excretions of certain types of frogs. The tip of the dart was rubbed across the frog's back where the poison was most concentrated. Poison-dart frogs were actually named after their use in the manufacture of darts and arrows. Some species of poison-dart frogs are among the deadliest animals in the world! The darts shown here are actually poisonous and have to be handled VERY carefully.
