A frog completely sheds its skin about once a week. After it pulls off the old, dead skin, the frog usually eats it.
When Darwin’s frog tadpoles hatch, a male frog swallows the tadpoles. He keeps the tiny amphibians in his vocal sac for about 60 days to allow them to grow. He then proceeds to cough up tiny, fully formed frogs.
When a frog swallows its prey, it blinks, which pushes its eyeballs down on top of the mouth to help push the food down its throat.
The wood frog of North America actually freezes in the winter and is reanimated in the spring. When temperatures fall, the wood frog’s body begins to shut down, and its breathing, heartbeat and muscle movements stop. The water in the frog’s cells freezes and is replaced with glucose and urea to keep cells from collapsing. When there’s a thaw, the frog’s warms up, its body functions resume and it hops off like nothing ever happened.
A group of birds is called a flock, a group of cattle is called a herd, but a group of frogs is called an army.
The glass frog has translucent skin, so you can see its internal organs, bones and muscles through its skin. You can even observe its heart beating and its stomach digesting food.
There is a frog in Indonesia that has no lungs – it breathes entirely through its skin.
The waxy monkey frog secretes a wax from its neck and uses its legs to rub that wax all over its body. The wax prevents the skin of the frog from drying out in sunlight.
Most frogs have teeth, although usually only on their upper jaw. The teeth are used to hold prey in place until the frog can swallow it.
The biggest frog in the world is the Goliath frog. It lives in West Africa and can measure more than a foot in length and weigh more than 7 pounds – as much as a newborn baby.
There’s a type of poison dart frog called the blue-jeans frog; it has a red body with blue legs. It is also sometimes called the strawberry dart frog.
The red-eyed tree frog lays its eggs on the underside of leaves that hang over water. When the eggs hatch, the tadpoles fall into the water below.
A frog is an amphibian.
More than 4,000 types of amphibians exist in this world, out of which only 45 species are found in Europe.
A frog is cold blooded (poikilothermic).
Frogs are unable to live in the sea or any salt water.
Frogs are able to lay 4,000 eggs at one time.
Frogs have webbed feet and long back legs which they use for jumping and swimming.
Frogs do not need to drink water, as they are able to absorb water through their skin.
A frog is able to change the color of its skin to match its surroundings.
The eyes and nose of a frog are located on top of its head. This feature enables it to breathe and see, when most of its body is submerged in water.
While under water, the frog’s eyes are protected by a transparent eyelid called a nictitating membrane.
Frogs use their long sticky tongue to capture their food.
Most frogs eat small insects like flies and cockroaches. The larger ones eat snakes, small mammals, birds and even other frogs.
The factors that determine a frog’s habitat are rainfall, soil type, places of refuge and calling and egg laying sites.
Each species of frog is blessed with a unique call, which is used to mark out a territory and attract females of the same species.
Frog eggs, or spawn undergo a change in body structure and physiology, from the tadpole stage to the adult frog stage.
Some frogs are able to jump up to 20 times their own body length in a single leap.
The Scottish highlands house the biggest frog.
A toad is dry and has warts. It prefers to walk instead of jump.
Goliath frog (Conraua goliath) from West Africa is the largest known frog with a body length that exceeds 30 cms.
The smallest frog that is known, is a Brazilian species (Psyllophryne didactyla) that has a maximum length of less than 1 cm.

About 88 % of amphibians are frogs.
Normally, frogs lay their eggs in water and their larvae, called tadpoles, develop in water only.
Though adults are carnivorous, tadpoles of most species are herbivorous and survive on algae that are passed on to the body through gills.
Frogs have a highly permeable skin that allows the passage of oxygen to the body and helps in breathing.
The skin permeability of frogs helps them absorb water directly through the skin.
The long hind legs of a frog, coupled with elongated anklebones, facilitate its jumping long distances.
The skin of frog is devoid of loose connective tissue that makes it slack and saggy.
Normally, skin texture of frogs varies, depending on the species, and can be smooth, crinkled or warty.
Frogs have three eyelid membranes, including a transparent one to guard eyes underwater.
Frogs have a hearing structure called tympanum, on each side of the head.
Frogs are normally toothless in the lower jaw and therefore, swallow their prey whole.
Frogs can easily camouflage, which serves as an important defensive mechanism.
The extent of webbing in toes of a frog depends on the amount of time it spends in the water.
Certain species, such as poison dart frogs, secrete mild poisons in their bodies. Some frogs also extract toxins from their diet.
Even though frogs are semi-aquatic, some species are also found in arid areas, such as deserts.
Frogs engage in calling behavior for a variety of reasons, including mating, territorial protection, distress calls and humidity cues.
Frogs breathe with three parts of their bodies: skin, mouth, and a membrane covering the inside of their mouths. Their skin takes in oxygen from their environment. They inhale and exhale through their mouths.
A frog’s sticky tongue is used like fly fishing. When it sees a meal, it casts out its tongue and reels it back in to swallow the meal.
Some frogs like the Squirrel Tree Frog have large sacs that expand to resonate sound. Some frogs can make sounds without any special sac.
Frogs call out for different reasons: mating calls, territorial calls, weather announcement calls, and cries for help.
Male frogs are the only ones who sing, to attract mates and warn off other males. Females listen to the mating song and choose a mate on which one is the loveliest.
