Golden poison dart frog

The golden poison dart frog is considered one of the most toxic animals on Earth. A single specimen measuring two inches (five centimeters) has enough venom to kill ten grown men. These brightly colored amphibians are among the largest of the more than 100 poison dart frog species, averaging more than one inch (two and a half centimeters) in length. They live within a tiny area of rain forest on the Pacific coast of Colombia. Though the population in its small range is abundant, widespread decimation of  its habitat has put this species on international endangered lists. Their coloring, which can be yellow, orange, or pale green, depending on their particular range, is deliberately ostentatious to ward off potential predators, a tactic called aposematic coloration. Their diet includes flies, crickets, ants, termites, and beetles.
