Frogs Interesting Facts
What type of animal are frogs?
Frogs are small semi-aquatic and insect-eating animals.
What class of animal do frogs belong to?
All frogs belong to the amphibian class. They can live both on land and in water. They are ectothermic or cold-blooded animals. Hence, they cannot regulate their body temperature and are suited only to their local marshy surroundings.
How many frogs are there in the world?
There are around 7000 species of frogs spread almost in all countries. There are many frog species like toads, tree frogs, green frogs, bullfrogs, wood frogs, horned frogs, African dwarf frogs, dart frogs, poison dart frogs, and goliath frogs.
Where do frogs live?
Frogs usually prefer living in warm and moist temperatures. Most widely found in the tropical rainforest, wetlands. In the cold American countries, frogs burrow under the ground for winter hibernation. Aquatic frogs and tree frog commonly found in tropical countries.
What is a frog's habitat?
These amphibians require a warm and moist environment to survive. They are ectothermic or cold-blooded animals who live on both lands and in water. The sultry climate helps them to retain the moisture on their skin. A female frog lays eggs in the water. After hatching the tadpole starts its life in the water eventually moving on to the land. A tree frog spends most of its life on a tree while frogs living in temperate American climates hibernate in winters burrowing under moist soil.
Who do frogs live with?
Frogs mostly live on their own, but can be found in packs during the rainy season or near a puddle of water. Frogs leap into people's houses, jump into tanks and adapts living well around people. The male frogs croak and become vocal while looking for a female to mate with. A frog's habitat comprises both its predators and prey.
How long do frogs live?
The lifespan of all the species of frogs ranges between one to eight years.
How do they reproduce?
During the spawning season, shortly after the rainy season, the male frog croaks and signals the female to mate. While mating, a male jumps on the back of a female clinging onto it with its hind legs. This position is scientifically called the amplexus. The fertilization process occurs externally, that is, it is done outside the female body. The fertilization occurs right after the females release their eggs for the males to fertilize. A single male frog gives out multiple mating calls and fertilizes numerous females in a day. It takes three to four days for the frog eggs to develop and within two weeks become tadpoles. One of the interesting facts is a frog's life cycle begins as a vegetarian. Once it becomes a full-grown frog, it turns into a carnivorous species.
What is their conservation status?
There are over 7000 frog species in the world. While most frogs are species of Least Concern, the Titicaca water frog is Critically Endangered as per the IUCN Red List. However, the American Museum of Natural History discovers and conducts modern research on the survival conditions, adaptations, threats, and conservation practices of this amphibian.
Frogs Fun Facts
What do frogs look like?
A frog's appearance usually has smooth and glossy-looking skin, greenish to dark green in color. Its eyes are big and neon yellow or red in color, protruding out from their chameleon-like small face. They barely have a neck and so cannot turn their heads. It has a wide torso with two front and two hind frogs legs. It has webbed feet, for clinging easily to slippery surfaces and swimming in the water. Its tongue takes up one-third of its body size, helping it to prey on flying insects easily. A toad is also a frog, but it is smaller and bulkier than a frog. The differences between frogs and toads are frogs have glossy skin while toads have a dry skin surface. The hind legs of a toad are smaller as they mostly live on land, unlike frogs which are semi-aquatic. A toad has a warty texture and darker color skin than a frog. The largest frog is the Goliath found in the African rainforests. The poison dart frogs are full of poison and exhibit beautiful colors like blue, red, and copper to ward off their predators.
How cute are they?
You can find a frog cute perhaps only because of its small size and for the way it jumps around. Some people find their vocal tune cute when a frog army croaks together.

A frog is a cute little species that often jumps into your home, backyard, and garden right after the rainy season. A tadpole is the cutest little amphibian, followed by the angry and cute-looking toad.

What are their male and female names of the species?
There are no specific names given to male and female frogs.
What would you call a baby frog?
Right after baby frogs hatch out from eggs, they are called polliwogs. Soon after their feet develop and they start to jump, they are known as tadpoles.
What do they eat?
Tadpoles are herbivores feeding on algae. Frogs are insectivorous. They prey on flies, mosquitoes, bugs.
Are they poisonous?
Every frog is poisonous to a certain degree. Their sloppy skin is filled with poisonous mucus protecting them from predators. Humans can feel skin irritation or develop an allergy after touching frogs. However, poison dart frogs and golden poison frogs are the most dangerous and poisonous frogs in the world.

Why do frogs scream?
Frogs scream to defend themselves from predators. Frogs scream at night to ward off danger and to feel safe. They start to shriek and scream when touched by humans. It is their way of saying "I'm not liking it so back off". After a rainy spell, we often hear frogs screaming and croaking. It is their search for a mate to unite with. To get rid of frogs and their constant screaming, you can trim your garden bushes and keep your pool clean. Also, spraying bleach and water mixture can effectively shoo away croaking frogs.
How do frogs breathe?
Tadpoles live in water and breathe through their gills. As it metamorphoses into a frog, it develops lungs and a vocal sac on the inner lining of the mouth. It gulps in oxygen which inflates the lungs and accommodates respiration. Since their lungs are not well developed, frogs can even breathe through their skin. The slimy permeable skin allows them to take in oxygen. An interesting fact is frogs can regulate the thickness of their skin underwater. Its skin becomes thinner when oxygen levels are low in the water and vice-versa.
