WHERE DO DART FROGS GET THEIR POISON?

• Poison dart frogs inhabit the rain forests of central and South America. 
• Their brilliant colors make them look their children's playthings, but they represent some of the most naturally toxic animals on Earth.
• Humans have learned to make use of their poison.
• The golden poison dart frog, for example grows only two inches long but contains enough venam to kill ten human beings 
• The Embera people of western Colombia use this frog's venom for hunting, spreading a tiny amount on a dart that they propel by blowgun into their prey.
• Scientists suspect that poison dart frogs gain their toxicity from alkaloids in the food they eat, including ants and mites. 
• Poison dart frogs raised in captivity and isolated from their native diet do not develop venam.
