in the wild a poison dart frog's colours shout «I taste horrible», and the golden poison frog of Colombia is one of the most poisonous animals on Earth. - [1](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/1/) — Zoo-bred dart frogs are harmless, because their poison comes from the ants and mites they eat in the wild, yet the keeper still wears gloves, this time to protect the frog's thin, damp skin, which it partly breathes through. - [2](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/2/) — A pink axolotl smiles from its tank with feathery gills like a baby that never grew up, and a sign warns that a fungus is killing frogs all over the world, so zoos keep rescue groups safe like a Noah's Ark. - [3](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/3/) — In the fairy tale a kiss turns a frog into a prince, but in real life kissing a frog or toad turns nothing into anything and some skins hurt your mouth, and no, holding a toad does not give you warts. - [4](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/4/) — Wild poison dart frogs have poison in their skin, and their bright colours warn predators; zoo-bred ones are not poisonous because their poison comes from the ants and mites they eat in the wild. - [5](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/5/) — The golden poison frog of Colombia is one of the most poisonous animals in the world, and some people in Colombia wiped darts on frogs' backs for hunting, which gave dart frogs their name. - [6](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/6/) — Frogs breathe and take in water partly through their thin, moist skin, so tanks are kept damp, and gloves protect their skin from the oils and soap on our hands. - [7](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/7/) — Chytrid fungus attacks frog skin and has killed frogs in many countries, wiping out some kinds; it spread partly when people moved frogs around the world. - [8](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/8/) — Zoos keep rescue groups of rare frogs in clean rooms until the wild is safe again. - [9](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/9/) — Axolotls are salamanders that keep their feathery gills and live in water all their lives; they come from lakes near Mexico City and are almost gone in the wild, though millions live in labs and homes. - [10](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/10/) — Axolotls can regrow lost legs and even parts of the heart and brain; they have three feathery gill stalks on each side of the head. - [11](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/11/) — The olm lives in dark caves in Slovenia and nearby; it has no colour, and its eyes are hidden under skin, because in total darkness eyes were no use and faded over many generations; it can live about 100 years. - [12](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/12/) — The Chinese giant salamander is the largest amphibian in the world, up to about 1.8 metres long, and is critically endangered from hunting and changed rivers. - [13](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/13/) — Male frogs fill a vocal sac with air to make their calls louder, telling females where they are and what kind of frog they are. - [14](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/14/) — Kissing a frog will not make a prince, and many toads have poison glands behind their eyes; dogs that bite cane toads in Australia can get very ill. - [15](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/15/) — Warts on people are caused by a virus that passes between people, not by toads; the bumps on a toad are glands. - [16](https://md.mova.elamur.ai/free/en/corpora/school/biology/89-amphibian-room-poison-frogs-axolotls-frog-rescue/16/) — Glass frogs have see-through bellies, and in 2022 scientists found that a sleeping glass frog hides most of its red blood in its liver to look almost clear. - ← previous: [The reptile house: Komodo dragons, chameleons, tortoises and crocodiles](https://md.mova.elamur.ai/free/en/corpora/school/biology/88-reptile-house-komodo-chameleons-tortoises-crocodiles/) - next →: [The aquarium: the coral reef tank](https://md.mova.elamur.ai/free/en/corpora/school/biology/90-aquarium-the-coral-reef-tank/) - ↑ back to [Biology](https://md.mova.elamur.ai/free/en/corpora/school/biology/)
