The dyeing poison dart frog is a small, brightly marked frog from the rainforests of north-eastern South America. It is one of the largest poison dart frogs and one of the most colourful, with more than 30 recognised colour forms. Its skin contains toxins, so it is a frog to admire from a distance.1

Poder do veleno

Veleno na pel

A súa pel é velenosa. É perigoso tocalo, lambelo ou comelo.

Que fai o seu veleno?

Its skin secretions contain alkaloids, which are toxic chemicals that interfere with nerve and muscle tissue. They can cause pain, cramping and stiffness, and in severe cases locomotor difficulties, convulsions, paralysis or death. In a reported case in Brazil, two men who handled the frog felt numbness within about 20 minutes, and the symptoms had gone after 40 minutes.1

Que perigoso é para as persoas?

Perigo para as persoas: DolorosoPode doer moito, pero case nunca é grave.

The frog is toxic if eaten, and its skin toxins can affect anyone who handles it. In a reported case, two adult male photographers in the Brazilian Amazon both had mild numbness that passed within 40 minutes. Their symptoms could have been worse with longer contact or if there had been a wound where they touched the frog.1

Que fai cando ten medo?

Its bright colours warn predators that its skin secretions are unpleasant, and predators that bite it tend to link the colours with the pain.1

Datos

It does not make its own poison. It gets the alkaloids from the ants and mites it eats.1

More than 30 colour forms, or morphs, have been recognised, and most are tied to a particular place.1

It is among the largest and most variably coloured of all poison dart frogs.1

Despite the huge variation in colour, the genetic differences between its populations are very small.1

It often lives in canopy gaps in the Amazon rainforest, where fallen trees hold water for its tadpoles.1
