The golden poison dart frog is known as not only the most poisonous of its kind, but also one of the most deadliest animals on the planet. One frog is said to contain enough poison to kill ten grown men, but they only average 2.5 centimetres (an inch) in length.
Despite these tiny dimensions, they’re actually the largest of over 100 species of poison dart frog and live in the rainforests of Colombia. This highly toxic frog was given its name after the indigenous hunters used its toxins to coat their darts. Deadly to the touch, the frog’s vivid yellow skin is a deterrent to scare off predators, but it only uses the poison in self-defence and not as a way to kill prey.
