Frog Fact #1 The smallest frog in the world is the Brazilian brachycephalid toad. This toad grows no longer than 3/8 of an inch!
Frog Fact #2: In the Middle and Dark Ages, a throat infection was treated by having the patient partially swallow a live frog. Supposedly, the frog would inhale the poisons of the disease. Remnants of this idea remain with the phrase, “A frog in your throat.”
Frog Fact #3: In South America, horned frogs are called escuerzos, and are thought to be evil spirits. They are thought to be able to kill livestock by biting the lips of the cow or goat and hanging on until the animal dies of starvation. Another legend says that if a person is bitten, the frog will not drop off or let go until after sundown.
Frog Fact #4: The world’s largest frog is the goliath frog of West Africa—it can grow to 15 inches and weigh up to 7 pounds.
Frog Fact #5: Frogs have excellent night vision and are very sensitive to movement. The bulging eyes of most frogs allow them to see in front, to the sides, and partially behind them. When a frog swallows food, it pulls its eyes down into the roof of its mouth, to help push the food down its throat.
Frog Fact #6: Frogs were the first land animals with vocal cords. Male frogs have vocal sacs—pouches of skin that fill with air. These balloons resonate sounds like a megaphone, and some frog sounds can be heard from a mile away.
Frog Fact #7: Launched by their long legs, many frogs can leap more than 20 times their body length.
Frog Fact #8: Many poisonous frogs, such as the golden poison frog and dyeing poison frog, are boldly colored to warn predators of their dangerous toxic skins. Some colorful frogs, such as the Fort Randolph robber frog, have developed the same coloring as a coexisting poisonous species. Although their skins are not toxic, these mimics may gain protection from predators by looking dangerous.
Frog Fact #9: There is evidence that frogs have roamed the Earth for more than 200 million years, at least as long as the dinosaurs.
Frog Fact #10: The Australian water-holding frog is a desert dweller that can wait up to seven years for rain. It burrows underground and surrounds itself in a transparent cocoon made of its own shed skin.
