frogs

 

Amphibians are: the smallest types of vertebrates and include four thousand species. 

 

They are animals that live a double life, where they live part of their life in water, breathe through gills, and live the other part on land after the formation of their lungs. Amphibians return to the water in the breeding season, and they are animals that do not have a tail except for salamanders, and some types of them maintain gills throughout their lives, such as water salamanders.

 

 Amphibians vary in their sizes, some are very small, up to one centimeter in length, and others reach one hundred and seventy centimeters, such as salamanders.

 The most important characteristics of amphibians

 

  • Their bodies do not have a neck except for salamanders.

 

  • Her eyes are surrounded by two moving eyelids.

 

  •   Its skin is smooth and moist because it contains many glands, and there are no scales on it, and some of it may have toxic glands.

 

  • The nostrils are connected to the oral cavity and have valves to remove water, which helps in pulmonary respiration in adults.

 

  •   Breathe through the skin or gills.

frog body

 

The body of the frog is divided into a head and a torso, and there is no neck or tail in the adult animal. 

 

The head is triangular in shape and contains a wide mouth opening, followed by two nostrils, then two large spherical eyes with upper and lower eyelids, and behind each eye there is a membrane of the eardrum, and behind it from the top There are parotid glands, which are poisonous glands in their secretions that kill germs that attack the skin of the frog, and these secretions make the frog taste unpalatable to its enemies.

 

 The body of the frog is covered with smooth, moist, sticky skin, mottled with dark green spots.

 

 It has several functions, which are protection from creatures, disease-causing germs, breathing and sensation, and the skin has the ability to absorb water because the frog does not drink.

Where does the frog live

 

Frogs have sixty families and differ from one species to another by the nature of their life, some of them live in swamps, in places of water gatherings, and in shallow rivers, and some of them live on the forest floor, and we also find a family called the atheropidus on the treetops where they live among the air plants.

frog life cycle

 

The female frog lays her eggs in large quantities in the water, and she does not need fresh water. 

 

In less than twenty days, the fetus turns from a few cells to a complete frog inside its transparent ball.

 

 God has created the various capabilities of frogs to live outside the water, the egg hatches and the tadpole or the so-called tadpole comes out of it to live in the water and breathe through the gills. To be able to live on land and then become a fully grown frog.

What do frogs eat

 

The larva of the frog or tadpole feeds on plants in the early stages of its life, but with time it becomes a carnivore.

 

 There are some types of frogs whose larvae are famous for their gluttony, such as the larvae of the frog known as Bufo nebulifer, where the larva can eat an earthworm within one hour,

 

 The larvae of the African giant frog also feed on other, smaller, weaker larvae. Adult frogs feed on a wide variety of organisms, such as spiders, worms, insects, snails, small fish, and even mice, and they may sometimes feed on plants. 

 

To the inside of the mouth and fix it by the upper jaw, and swallow it without chewing, because the mouth of the frog lacks the presence of teeth, when swallowing food, it is noticed that the frog’s eyes retract back and slide inside the bones of the skull to push the food down the throat.

 

Most frogs hide and wait for prey to approach them, but some types of frogs ambush their prey, as do the frogs known scientifically as ceratophrys ornata, they extend their yellow feet, and start shaking them to attract their prey, which may be frogs of the same species. 

 

On the other hand, frogs are a potential meal for many living creatures, such as seagulls, hawks, snakes, foxes, dogs, sea bass, sharks, and even humans. Frog legs are a famous meal in many countries of the world.

frogs in the environment

 

Frogs are of great importance in the ecosystem, as they feed on insects and others, as they are a food source for many living organisms, so they had to develop their defenses to protect them from predators, and help them survive, including their ability to escape quickly, or pretend Some species use their colors to disguise, and to frighten enemies, such as the frog that is scientifically called Physalaemus nattereri. 

 

It has two spots near its hind legs that appear to predators as back eyes, which gives the frog a more threatening appearance than it is in fact, and some species such as a frog The poisonous frog can secrete a poison capable of killing a predator when touched. 

 

The poisonous frog’s ability to produce poison is due to its diet, as it feeds on ants, termites, and beetles.

 

 The indigenous people of Colombia used the poison secreted by the poison frog to paint their arrows while hunting, and many researches are underway to take advantage of these toxins in the production of pain-relieving drugs.

Frogs are exposed to many threats caused by humans. Some regions of the world have witnessed a noticeable decline in the number of frogs, due to several reasons, including loss of habitat as a result of projects that affect the flow of rivers and streams, in addition to acid rain, water contaminated with chemicals, and drug residues. Which causes problems for frogs, such as deformation of the limbs, and the presence of males bearing female characteristics.

 

Another danger that affects frogs is climate change, and global warming promotes the growth of a type of fungus called (The chytrid fungus), which is responsible for the death of millions of frogs around the world, and has caused the extinction of more than (100) species of frogs, and other amphibians. Since 1970, climatic changes have also caused a decrease in the number of frogs that live on mountaintops, because the rise in temperature pushes the clouds away from the wet leaves of plants on which the frogs lay their eggs, leaving them dry and unsuitable for laying eggs.
