I have never known much about any frog, let alone if they have hair, but I do know that from the moment someone asked me that I wanted to know everything about it. So, I went on the internet and did some research on it. Here is what I found.
So, Do frogs have hair? No, Anura (frogs and toads) do not have hair and don’t need hair to keep them warm. Frogs are cold-blooded and dependent on the environment to regulate their body temperature. Although there is a frog that technically has hair. The so-called Wolverine frog (Trichobatrachus robustus) has physical extensions of the skin that protrude in ridge-like shapes out of the surface.
With that said, some questions still remain. Why do frogs don’t have hair? What are hairy wolverine frogs, How do frogs protect themselves from the cold?
Why Frogs Don’t Have Hair
Simply put, frogs are amphibians and they don’t have hair. For us, humans, hair on the body plays an incredibly important role in regulating the temperature of our body. When it is cold, tiny muscles around the hairs cause the hair to stand up and so keep more heat near our body. Frogs don’t have hair because they don’t need to do that.
As you may know, frogs are cold-blooded. This means that the body of the frog is the same temperature as the environment. When the frog is cold, it will go to a warm place (say, a heat lamp) to warm up. When the frog gets too warm, it will go into the water or a surface that is cold to cool their bodies off.
If Frogs Don’t Have Hair, How Is The Skin Made Up?
There are a few things that you need to know about frog skin. The question “Do Frogs Have Hair?” is now been answered and it is simply a no. But how then is the skin made up? Frogs (and toads) have a “lycra” type kind of skin. This type of skin protects the frog from potential injuries and from diseases. The skin also has a respiratory function, helps control body temperature and it has many glands which can exude toxic and distasteful substances.
And, as you may know, frog skin comes in all sorts of amazing variations of colors and the patterns.
This skin of a frog doesn’t have these colors and patterns just for fun. The different skin patterns can help camouflage the frog and the color of the frog tells other animals to stay away from the frogs and let them know if they’re poisonous or not.
Another thing to know about the skin of a frog is the fact that it is permeable. This simply means that it can let water in and out. This is why frogs often don’t “drink” water. They can absorb the water through their skin.
How Do Frogs Keep Themselves Warm or Cold Without Hair
As you have read above, frogs are cold-blooded. They have the same temperature as their environment. When frogs get to warm they don’t start sweating… They go to a place that is cool to make their body temperature go down. When the frog gets cold, he just goes to a spot that is warm to up is body temperature. They don’t have to “protect” themselves from heat or cold. Some frogs are even freeze-tolerant”. This means that they can survive a winter being frozen and so live enough to mate another spring.
Is it Dangerous to Hold a Frog?
It can be dangerous to hold a frog. It can be dangerous for you, but also for the frog. For humans, it can be dangerous because amphibians have been known to carry the salmonella germ. If you don’t wash your hands after you hold a frog, you can get infected. Keep your hands away from your mouth and your eyes.
Holding frogs can also be dangerous for frogs. As you now know, frogs have very delicate skin. They also have the ability to absorb all sorts of substances through their skin (not only water). This means that lingering soap residue, oil, and other chemicals can also be absorbed by the frog.
Here is what you can do:
- Wash your hands – Wash your hands thoroughly to make sure that they are properly clean. Remove all the soap, sunscreen and other chemicals of your hands. Also, keep your hands wet when holding your frog.
- You can wear gloves – There are disposable gloves you can wear that protect both you and the frog from harmful toxins. Besides all this, it is also important to know that when holding your frog, you don’t hold him too tight. Holding him tight can result in much pain for your frog. Keep it light and gentle at all times!
Is There a Frog That Does Have Hair?
Yes, there is a type of frog that does have hair. Hairy frogs, also known as Wolverine frogs or horror frogs (Trichobatrachus robustus) are scary but certainly real. These frogs are a unique kind of amphibians that only live in Central Africa. At first glance, it looks like the wolverine frog has hair but technically this isn’t the case. The hairs you see are called dermal papillae. This is a fancy word for physical extensions of the skin. Do you want to know what the hairy frog eats? here is the answer: the hairy frog feeds himself on slugs, myriapods, spiders, beetles, and grasshoppers.
Does a frog have opposable thumbs? Most frogs do not have opposable thumbs. But there is a species in Central and South America that have opposable thumbs. They are called Phyllomedusa. This frog is also called leaf frog. They have this name because they lay their eggs on leaves.
Do frogs have ears? Frogs do not have external ears. But frogs can certainly hear. They have eardrums and an inner ear. You can see the ear of a frog by locating the circle behind a frog’s eye. This circle you see is also called tympanum.
Do frogs have ovaries? Female frogs do have two ovaries. They also have a pair of oviducts in their reproductive system which you can find beside the kidneys. The female frog produces about 2,000 to 20,000 eggs and retains them inside her body until mating seasons starts. If the mature eggs stay in the ovaries to long (even after breeding season), the eggs begin to deteriorate inside the body.
