Frogs and Toads

The Metamorphosis

Step by step, tadpoles develop into land animals: first, they start to grow two sets of legs, then their gills are reabsorbed and lungs are formed. Finally, skin and organs develop.

What Do Frogs Eat?

“Open wide!” When a frog swallows its prey, it closes its eyes and pulls them back into its head. Its eyes help to push the snack in the right direction, towards its stomach.

How Do Frogs Breathe?

Frogs breathe through their skin! They even drink through their skin.

How Long Do Frogs Live?

Frogs and toads live for between 4 and 15 years. The oldest toad lived to be 36. Other types that live very long:

  • Cane Toad: 10-15 years (record: 35 years)
  • Oriental Fire-Bellied Toad: 12-15 years
  • South American Horned Frog: 6-7 years (record: 10 years)

Do Frogs Have Ears?

Yes, but you might not notice them at first glance. They are on the side of their heads.

Do Frogs Have Teeth?

Yes, many frogs have teeth but not as many as we humans do. They have a row of small, rootless teeth on their upper jaw that you can hardly see. Some frogs even have mini “fangs”. They hold their prey with their blunt, little teeth. But they wouldn’t even be able to scratch a human. Toads NEVER have teeth.

Which Are the Enemies Frogs and Toads?

Frogs and toads are on the menu for snakes, lizards, birds and hedgehogs. Their biggest “enemy”, however, is increasing environmental pollution caused by cars, which also run over countless animals each spring as the frogs migrate.
