The green and black poison dart frog ( Dendrobates auratus ) is a Froschlurch from the family of the poison dart frog (Dendrobatidae).
description
The attractively colored gold tree climbers secrete toxins through their skin, which they only have in the wild. By eating poisonous ants, they transform the insects' poisons into poisonous secretions, which are then secreted through the skin.
Like many of its relatives, the frog is characterized by a very lively body color that acts as a warning. The wealth of colors goes from black / green, with many different shades of green and deviations in the green / black component (e.g. Costa Rica, Pacific side, with predominantly black, and Caribbean side with predominant green), golden / brown and blue / black to almost completely yellow animals.
Occurrence
The species occurs in tropical Latin America , for example in Costa Rica , Panama and Colombia . You can find them at altitudes up to 1000 m. It was also released in the early 1930s on the Hawaiian island of Oahu for mosquito control.
Way of life
food
Depending on the stage of development, the larvae of the gold tree climber feed on detritus in their natural habitat , and later on insect larvae that develop in the temporary waters. They have the function of a top predator in these phytotelms , although they sometimes compete for food with dragonfly larvae . When rearing in the aqua-terrarium, they also accept dry food for ornamental fish.
Reproduction

The female only lays four to six eggs on damp leaves. Goldbaumsteiger practice brood care by the male taking a hatched tadpole on his back and then depositing it in water-filled leaf axils of bromeliads , which are about two to three meters above the ground.
Brood care includes watering the clutch as well as transporting and placing the tadpoles in water. Due to their occurrence near streams and pools of water, the tadpoles are transported in small pools of water. Often water-filled cavities are used here. B. in branch, root caves or bromeliad funnels as a nursery. The male always transports 1–3 tadpoles on his back. After that, brood care ends. The search for suitable temporary bodies of water, in which the offspring can find sufficient water and food for the entire development period, and remain unmolested by predators , is one of the great orientation efforts of these frogs, which has not yet been adequately investigated. If the tadpoles were not separated from each other, cannibalism could result, in which the stronger larvae eat the weaker ones.
Duration
The size of the stocks and their development are only insufficiently known, but the IUCN considers the gold tree climber to be safe.
Systematics and taxonomy
The species was described as Phyllobates auratus in 1855 by the zoologist Charles Frédéric Girard , who came from Mühlhausen in Alsace, but who worked in the USA . After several name changes, the American herpetologist Emmett Reid Dunn gave it its current name in 1941 .
