Scientists classify frogs as tailless amphibians. That is, they are animals that can live in water and on the ground. In total, there are more than 500 species of frogs. They live everywhere, all over the world, except in the far north. Most of them are found in tropical forests, as they are always damp and warm.
Frogs are separated by habitat. There are wood, water and land frogs. The waterfrogs have eardrums on their feet for swimming. The woody ones have special cushions, with the help of which they hold well on the tree. Some tree frogs have special membranes on their feet and folds of skin on their sides, which allows them to "fly". They jump from tree to tree and use these devices to plan. There are no eardrums or pads on the ground, and the paws are very well developed, as movement on the ground is very difficult. Frogs are good jumpers. Compared to their body length, they jump very far and very quickly.
The biggest frog is the goliaf frog. Its length is 32 centimeters. The smallest is the leaf frog. It is only 2 centimeters in size. But most of the time the size of these amphibians is from seven to fifteen centimetres. The skin of all frogs is covered with special slime. It protects the skin from harmful germs and helps heal wounds. In some species, this slime is poisonous. This is how they protect themselves from their enemies. Most often they are tree frogs, which are found in the tropics.
These animals eat small insects: dragonflies, flies, mosquitoes. Most frogs have a long, sticky tongue, which helps them to catch food. The tongue moves very fast and has time to catch an insect on the fly. Large individuals can catch a small snake, a chick or a friend of a small frog.
The frog multiplies by laying eggs. Tadpoles hatch out of the eggs after about 10 days. They are called that because they only have a head and a tail. Gradually tadpoles grow and change: their feet grow and their tail falls off. After four months they turn into a frog.
Each frog species quacks in its own way. Sometimes these sounds are so loud that you can hear them from a mile away.
Some frogs are turned on like pets and kept in an aquarium.
Interesting facts:
Our great-grandparents threw frogs into the milk and it didn't sour because the skin of these animals kills bacteria.
The frog's eyes are located on the sides and it can see in several directions at once - sideways, upwards, forward.
Even when sleeping, their eyes do not close, but are covered with a special film - the inner eyelid.
Frogs are part of a group of animals that are considered to be non-tailed amphibians, and scientists have more than 2000 species. Amphibians have two ways of breathing: pulmonary on land and skin under water.
Frogs have a small head with convex and protruding eyes and a large mouth. The animal has a compacted torso, small front legs and powerful hind legs. There are eardrums between the fingers that are suitable for swimming. The skin of frogs is damp and covered with slime, which is secreted by the skin glands. Mudslide of frogs promotes gas exchange, has antibacterial properties and protects the skin of the animal from drying out. Some glands secrete poisonous secrets that protect the animal from attack by predators. Water can also enter the body through the skin surface, so they lose the need to drink while in the water. The color of frogs is very diverse, as well as its purpose. With the help of coloring, some frogs are disguised as the environment, while others warn about their poisonous appearance.
Frogs live in many places around the globe. The main factors for their lives are humidity and the presence of water bodies. Tropical forests are particularly diverse in terms of species, as the local climate provides them with favourable living conditions.
The frog is very active during the warm season. But in sunny weather they prefer to sit in the shade, because the sun dries out a layer of slime on their skin, and this can cause death to the animal. When it gets cold, frogs hide or hibernate, hiding at the bottom of a water body or under fallen leaves. Frogs hibernate to withstand adverse conditions.
Flies, flies, flies and other insects are the mainstay of frogs, sometimes they can eat fish fry, spiders or snails. They hunt in the water or on land, and if a frog notices its prey, it quickly throws its tongue covered with sticky substance to it and sticks to the prey.
When the mating period comes, both sexes gather at water bodies with fresh water. At first, males appear to attract the female, and they cry loudly. Females come to the call and later postpone the eggs. Frog larvae - tadpoles - develop from eggs. They are very different from adults in their way of life and appearance. Most tadpoles eat algae. After a certain period of time they turn into adult frogs.
