The world’s largest frog is the goliath frog of West Africa, which can grow up to 15 inches in length and weigh up to 7 pounds. This unique creature has vocal sacs, pouches of skin that fill with air and resonate sounds like a megaphone. This adaptation helps them produce loud sounds, with some frog calls being audible from miles away.
On the other hand, at 7mm (0.27 inches) long, the Paedophryne amauensis frog from eastern Papua New Guinea is considered the smallest frog in the world. Many poisonous frogs, such as the golden poison frog and dyeing poison frog, have bold and bright colors to warn predators of their toxic skins. These creatures are small but deadly, making them a fascinating subject for researchers and naturalists alike.
In another part of the world, the wood frog has a unique adaptation that allows it to survive in extremely cold environments like the Arctic circle. This remarkable creature can live with 65% of its body frozen thanks to glucose in its blood acting as antifreeze that protects its vital organs from damage. The wood frog’s ability to survive in freezing temperatures for extended periods is nothing short of miraculous.
