Here are some wild and little-known frog and toad facts that will blow your minds:

1. Frogs can "freeze solid" and come back to life

Wood frogs in North America can literally freeze in winter—heart stopped, no breathing—and thaw out in spring as if nothing happened. Their bodies use glucose as a natural antifreeze.

2 They breathe through their skin (and some don’t have lungs at all!)

Most frogs can absorb oxygen directly through their skin. Some species, like the Bornean flat-headed frog (Barbourula kalimantanensis), have no lungs whatsoever—they survive entirely by breathing through their skin.

3. Toads can squirt poison from their bones

The Iberian ribbed newt (not a toad, but close amphibian kin) can push its rib bones through its skin coated with poison as a defense. Similarly, cane toads secrete a toxin strong enough to kill predators (and has even harmed pets and humans).

4. Frogs can shoot their tongues faster than you can blink

A frog’s tongue can strike prey in less than 0.07 seconds—about five times faster than a human eye blink. The tongue is also coated in one of the stickiest biological substances known.

5. Some frogs give birth through their stomachs

The now-extinct gastric-brooding frogs of Australia (Rheobatrachus) swallowed their fertilized eggs. The mother shut down stomach acid, turned her belly into a womb, and birthed live froglets from her mouth.

6. Toads have “ear drums” on the outside of their heads

That round disk behind their eyes is called a tympanum. It works like an ear drum—picking up sound vibrations. In some species, the tympanum size can even tell you if it’s a male or female.

7. Frogs can change their color with mood and temperature

The gray tree frog, for instance, shifts from green to gray depending on stress, temperature, or surroundings. It’s like natural mood-ring camouflage.

8. They can "play dead" dramatically

When threatened, some toads flip onto their backs, stick out their tongues, and remain motionless—like a little amphibian Oscar performance—to trick predators into thinking they’re already dead.

9. Frogs have teeth—but only on the top!

Most frogs have tiny maxillary teeth on the upper jaw. They don’t chew—teeth just help hold wriggling prey while they swallow it whole. Toads usually don’t have teeth at all.

10. The loudest frog is as loud as a chainsaw

The male Puerto Rican coquí frog can produce calls at 100+ decibels—about as loud as a jackhammer—to attract mates. Imagine hearing that all night in the rainforest!
