The Poison Dart Frog is one of the Amazon's most amazing creatures. These extraordinary amphibians have evolved to live in the Amazon. . A recently published study by Wang and Shaffer found that poison dart frogs have evolved to be more poisonous and colorful. These 6 cm amphibians were dying off due to larger hunters that fed on them. The poison dart frog was already acidic but even with this unusual weapon they still could not defend themselves. So this creature evolved to be more poisonous and deadly. The colour of their skin brightened to warn off predators and the toxicity of their poison increased. Some of these poison dart frogs evolved to be nocturnal. This transformation has changed the poison dart frogs habit exponentially. The change has caused the frog to prey on different animals forcing them to change their dietary habits. Also the evolutionary change allowed the frogs to reproduce successfully without being in grave danger.
