Facts about frogs

January 23, 2018 GMT

A frog is an amphibian. It lays eggs in water where they hatch into tadpoles that live in water until they metamorphose into adult frogs.

Tree frogs have developed disks or suction pads on the toes of their feet to help them climb.

Frogs have long back legs and webbed feet for jumping and swimming.

A frog can change the color of its skin depending on its surroundings.

The Golden Dart Frog is the most poisonous frog on Earth. The skin of one such frog could kill up to 1,000 people.

The eyes and nose of a frog are on top of its head so it can breathe and see when most of its body is under water.

People who study frogs and toads are called herpetologists. Herpetology is the study of amphibians and reptiles.

Many brightly colored tropical frogs, such as the dart frogs, are colored to warn predators that they are poisonous.

Some frogs can live in environments well below freezing. The Gray Treefrog, for example, can survive even though its heart stops. It does this by making its own antifreeze, which stops its body from totally freezing.


Tadpoles look more like fish than frogs, as they have long finned tails and breathe through gills.

An amphibian can live both on land and in water.

Although frogs live on land, their habitat must be near swamps, ponds or in a damp place. This is because they will die if their skin dries out.

Instead of drinking water, frogs soak the moisture into their body through their skin.

Frogs breathe through their nostrils while also absorbing about half the air they need through their skin.

Frogs use their sticky, muscular tongue to catch and swallow food. Unlike humans, their tongue is not attached to the back of its mouth. Instead it is attached to the front, enabling the frog to stick its tongue out much further.

The common pond frog is ready to breed when it is only 3 years old.

Frogs in the wild face many dangers and are lucky to survive several years. In captivity however, frogs can live for much longer.

Frogs can see forwards, sideways and upwards all at the same time. They never close their eyes, even when they sleep.

Remarkably, frogs actually use their eyes to help them swallow food. When the frog blinks, its eyeballs are pushed downward creating a bulge in the roof of its mouth. This bulge squeezes the food down the back of the frog’s throat.
