In fact, the skin secretion of the true poison dart frog, or golden poison frog ( Phyllobates terribilis), is so toxic that the tip of a dart rubbed across its back picks up sufficient poison to kill a large bird or a monkey. Nonetheless, handling one of the brightly coloured dendrobatids, such as Dendrobates and Phyllobates, requires caution because their alkaloid skin secretions are potentially lethal if absorbed through human mucous membranes or passed into the body through a cut on the skin. Harlequin poison dart frog © Anyka/FotoliaĪll frogs (order Anura) produce poisonous skin secretions however, humans do not notice the toxicity or suffer skin irritation when handling most species.

These compounds are then transferred into the frog’s skin glands where they are stored and secreted when threatened. These smaller creatures biosynthesize the toxic compounds from things they eat on the forest floor, such as decaying plant material. In the wild, the frogs eat ants, millipedes, mites and other arthropods that have toxic alkaloids naturally occurring in their skin. Due to not absorbing the toxins through their diet the frogs lose the ability to secrete it through their skin. The toxin filled beetles and ants are replaced by flies, mealworms and crickets – all of which are completely non-toxic. When one of these frogs is kept in captivity, however, their diet is often changed. The frogs have evolved to be immune to the effects of the toxin but will secrete them through their skin if in distress. These all exhibit the same type of toxins that the frogs secrete. The frogs eat certain species of ants as well as some beetles. However, when in captivity, the frogs are no longer poisonous. The poison dart frog will secrete toxins through its skin if threatened, which are so deadly that any contact with humans or mammals will cause death. However, when kept in captivity the poisonous nature of the frog completely disappears. The indigenous people of South America used their toxin to poison the tips of their blow darts which would kill any animal or person it hit.

Two micrograms of their toxin (an amount that would fit on the head of a pin) would be enough to kill a person. While only around 5cm long, the Poison Dart Frog has enough venom to kill 10 adult humans. One of the most poisonous animals on Earth is the Poison Dart Frog.
