Dyeing poison dart frog

Dendrobates tinctorius

名字的由來： 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

只是會痛不要碰會痛，但不會對你造成嚴重傷害。

箭毒蛙、蟾蜍和蠑螈

皮膚裡有毒吃：昆蟲有毒（碰或吃會中毒），不是有毒液

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

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

有毒還是有毒液？有毒液的動物會用咬或螫把毒液注入身體。有毒的動物則是碰到或吃下去會有害。這種動物是有毒的（碰或吃會中毒）。

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

3,5 cm 到 7 cm (1,4 in 到 2,8 in)1

牠吃什麼？

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

怎麼認出牠

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

毒素力量

皮膚裡有毒

牠的皮膚有毒。碰、舔或吃牠都很危險。

牠的毒素有什麼作用？

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

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

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
