Dyeing poison dart frog

Dendrobates tinctorius

名字的由来： The specific name tinctorius does not refer to its colours. It comes from legends of some indigenous tribes, who said they used frog poisons to make green parrot feathers grow in different colours.1

皮肤里有毒吃：昆虫碰了或吃了有毒，不注射毒液

对人的危险: 很疼可能真的很疼，但几乎从不严重。

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

It lives in patches of tropical primary rainforest, mostly in hilly or upland areas, at altitudes up to 600 m, though some populations are found at sea level. It is often found in canopy gaps, where trees have fallen, and it uses water-filled spaces on fallen trees for its tadpoles.1

它吃什么？

It eats small arthropods, mainly ants and mites. It mostly stays on the ground, where catching prey is easier, though it sometimes climbs trees.1

怎样认出它

The body is mostly black, with an irregular pattern of yellow or whitish stripes along the back, upper flanks and head.1
The lower flanks, belly and throat have irregular blue stripes, and the legs are blue with small black specks.1
The blue ranges from pale sky blue to royal, cobalt or navy blue, and some colour forms are mostly yellow, mostly blue or mostly whitish.1
Adults usually measure around 5 cm from snout to vent. Females have circular toe discs and arched backs, while males are smaller and more slender, with heart-shaped toe discs and curved backs.1

毒力

皮肤里有毒

它的皮肤有毒。摸、舔或吃都很危险。

它的毒会造成什么？

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

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

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
