The native people of the Amazon region who hunt with blow guns for animals in the top of the rainforest canopy coat their darts with the skin of these frogs...hence their name, Poison Dart Frogs. Very small, they are reputed to have the most toxic poison in the world. They are maybe an inch, or a little more, long. They live in the rain forests of Central and South America. It was pretty dark in their environment, so as y;all can see, I kind of had to push the ISO.
