Frog Anatomy in 3D: Skeleton, Organs and Breathing Through Skin
Frogs are amphibians that live a double life in water and on land. They breathe through their skin as well as their lungs and leap with long, powerful back legs. In the 3D Animal Anatomy simulator you can turn a frog around, look inside and see its skeleton.

The frog skeleton
A frog's skeleton is short and built for jumping. It has a short spine, usually no ribs, and very long back leg bones that fold up like a spring, ready to launch.
Inside the frog
In the Inside view you can tap these labels on the 3D model:
- Brain
- Controls every move, sense and thought.
- Heart
- Pumps blood around the whole body, all day and night.
- Lungs
- Small lungs. Frogs also breathe through their skin.
- Intestines
- Long tubes that soak up food into the body.

Why do frogs blink when they swallow?
Their eyes sink down into the head and help push food down the throat.
Do frogs drink water?
Not with their mouths. They absorb water through their skin.
