Sapo-flechas-de-veneno (Dendrobatidae) (Poison dart frog, also dart-poison frog, poison frog or formerly poison arrow frog) is the common name of a group of frogs in the family of amphibians frogs belonging to the order anura, suborder Neobatrachia. Members of this group have the particularity of producing potent toxins that are in your skin. The species with the most poisonous toxin is Phyllobates terribilis, which matches with the wasp venom of the sea. More than 100 toxins have been identified in skin secretions of members of this group, especially in the genus Dendrobates and Phyllobates. Members of the latter genus produce a potent neurotoxin called batracotoxina. Just 40 micrograms of this substance can be fatal. Some tribes of Sapo-flechas-de-veneno in South America use these toxins, placing the tip of the arrows used in hunting, hence the name poison dart frogs in English. Some species acquire the ability to produce toxins in part due to the ingestion of ants. These ants, in turn, feed on plant species with toxic property.
