How Many Toes Do Frogs Have? The Interesting Answer
Updated on
Some swear it’s four, others swear it’s five–but exactly how many toes does a frog have? Frogs have five toes on each hind leg, equaling ten toes total. As for the front legs, most frogs have four fingers on each hand; however, some species have five on each hand. The exceptions are the Dagger frog (Babina holsti) and the Otton frog (Babina subaspera), which are Japanese Ranid frogs.
If you want to learn more about various frog toe formations and their unique functions, keep reading below. Even better, we’ll be talking about the unique frog anatomy and some fun frog facts that you may be surprised to learn.
Different Frog Toes
Not all frog toes are created identically, and different toe formations are helpful for different functions.
- Webbed feet: Many aquatic frogs have webbed structures between their toes to aid them in rapid, powerful swimming. Sometimes, webbed feet can help frogs soar through the air, as the webbing acts like a parachute.
- Suction-cup feet: Tree frogs tend to have rounded, suction-cup pads on their toes to help them cling to trees as they bounce from branch to branch.
More About Frog Anatomy
Frogs have fascinating anatomy. Although every species is unique, there are some general anatomic characteristics and functions that most frogs share.
Vision
Frogs are known for their remarkable nighttime vision. They are incredibly sensitive to movement, and their bulging eyes allow them to see in all directions–even behind them!
Their eyes are so powerful that they aren’t just used for vision. When frogs swallow their food, they use their eyes to push their meal down their throat. This is done by dropping the eyes down into the roof of the mouth, putting pressure on whatever is inside.
Vocal Cords
It is believed that frogs were the first land amphibians to develop vocal cords. In male frogs, there is a structure known as the vocal sac, which is a pouch of skin that can fill with air. These vocal sacs create a resonating sound that can sometimes be heard from around a mile away.
Legs
A frog’s legs contain a tremendous amount of power. When launching, many frogs can jump a distance that spans over 20 copies of their own body combined!
Skin
Different species have different skin types, but they all contribute to unique and fascinating functions. For instance, some frogs may look plain and muddy brown, but this simple color camouflages the frog from predators or prey. On the other hand, vibrantly colorful frogs can scare off predators by convincing other animals that they are poisonous–even if they aren’t.
