Sci-Frog | The Hindu Science Quiz: Ribbiting Facts about Frogs

From the vast African continent, the goliath frog reigns supreme as the largest amphibian on earth. This impressive creature can grow up to 15 inches in length and weigh up to 7 pounds. What makes this frog so unique is its vocal sacs, pouches of skin that fill with air and produce sounds like a megaphone. With some frog calls being audible from miles away, these vocal sacs are a vital tool for male goliath frogs to attract mates and ward off predators.

On the other end of the spectrum, we find the Paedophryne amauensis frog from eastern Papua New Guinea. At just 7mm (0.27 inches) long, this tiny creature holds the record for being the smallest frog in the world. Despite its minuscule size, this frog still boasts bright colors and patterns that serve as a warning to predators about its toxic skin. Poisonous frogs like the golden poison dart frog and dyeing poison dart frog use bold colors to alert predators of their dangerous skins.

In colder environments like the Arctic circle, it’s no easy feat to survive. That’s why the wood frog has developed an incredible adaptation that allows it to thrive in extreme cold conditions. This remarkable creature can live with up to 65% of its body frozen thanks to glucose in its blood acting as antifreeze that protects its vital organs from damage. Thanks to this adaptation, wood frogs can endure freezing temperatures for extended periods without suffering any harm.
