Despite what internet memes featuring green anthropomorphic amphibians would have us believe, here’s the real tea: Frogs are generally known to absorb water through their skin instead of drinking it.

A frog’s skin is permeable, particularly near its belly and thighs, allowing it to absorb water from its environment into its body. Furthermore, glands located all over the frog secrete mucus, keeping its skin moist and slippery while also letting it take in oxygen and expel carbon dioxide. Frogs share this trait with other amphibians as well.

However, this characteristic also makes frogs and other amphibians particularly vulnerable. Once a frog’s skin dries out, it severely affects the amphibian’s ability to respire, resulting in its death.

Admittedly, it’s a rather strange adaptation—one that further sets amphibians apart from other animals. But hey, that’s none of our business. 🐸🍵
