All animals adapt to survive in the wild, and frogs are no exception. Here is a list of the top ten physical adaptations that enable frogs to thrive in wetlands.
1. Legs: Frogs have very powerful back legs and webbed feet that help them swim and jump.
2. Skin: Frogs can breathe though their skin so they can stay underwater as long as they want.
3. Skin: Frogs don’t drink water through their mouths at all, instead they soak it into their bodies through their skin.
4. Skin: Frog skin is often camouflaged to hide from predators. Some frogs can change the colour of their skin depending on its surroundings.
5. Skin: Some frogs secrete poison through their skin. Many of the more easily visible, brightly colored tropical frogs are colored in this way to warn predators that they are poisonous.
6. Croaks: Frogs attract each other for mating with their croak. Each frog species has a distinct croak. They have vocal sacs, which fill with air, and can amplify the sound up to a mile away.
7. Tongue: When a frog spots a tasty meal, it flicks out its long, sticky tongue. The tongue wraps around the meal/insect and pulls it back into the frog’s mouth. Unlike humans, a frog’s 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.
9. Eyes: Frogs swallow using their eyes. Its eyes retract into its head and push the food down its throat. Frog’ eyes are on top of their heads so when they swim close to the surface of the water, only their eyes are exposed. This way, they can quickly spot danger before danger spots them.
10. Eyes: Frogs can see forwards, sideways and upwards all at the same time and never close their eyes, even when they sleep. They even have a third eyelid which is see-through and protects the frog’s sensitive eyes when it is under water.
