Amphibians

The meaning of "amphibian" as "double life" means the fact that most adult amphibians live on land and the embryos need water to survive. Some amphibians have appeared since the Jurassic, but the number of these longevity animals has declined worldwide (amphibians). As of 2010, 32% of the world's 6,600 amphibians are in danger of extinction (Hayes, Falso, Gallipeau, Stice 2010). Although there is no reason for the reduction of amphibians, as with deforestation, the main cause of human influence, including urbanization, forest fragmentation, predation, human development, pathogen and climate change is the loss of habitat (Hayes, Falso, Gallipeau). , Stice 2010).

Amphibians are composed of three groups of vertebrates, frogs, baboons and marmosets (only found in tropical regions). Amphibians have smooth, unscaled skin that permeates the water. Water may evaporate easily from the skin, and if water is not available, amphibian dries and dies within hours. Therefore, when evaporation is minimized, amphibians tend to become active: when the night and it rains. However, this same skin permeability allows amphibians to obtain moisture from sources other than pools. This means that amphibians can live in a very dry climate like the desert, and when the dry season comes, they simply drill holes in the ground and absorb water from the surrounding soil. Nevertheless, the relationship between amphibian and water still exists: In order to survive, their eggs must be placed underwater.

Reptiles and amphibians have big physical differences. Reptiles have dry scaly skin, but amphibians are moist and sometimes quite viscous. They are vertebrates, cold-blooded like amphibians. Amphibians are smoother than reptiles. Unlike reptiles, most amphibian skin is not waterproof. Most amphibians have lungs, but they usually breathe through the skin and mouth, but most reptiles do not breathe. Most amphibians have limbs. Limbs and lungs are adapted to adapt to living on land and to distinguish them from reptiles.

The field of zoology in which amphibians and reptiles are involved is called reptilianology. The study of amphibians is called Butler Collage. Examples of amphibians are frogs, crickets, crickets, crickets and apes. Reptiles include turtles and turtles, lizards, snakes, crocodiles and crocodiles, sea turtles and big lizards

For a while, reptiles and amphibians have been zoologically classified as reptiles due to their many similarities. It is speculated that reptiles changed from amphibians about 50 million years ago. Let's first examine the similarity between reptiles and amphibians. Defensive Features: Both reptiles and amphibians use camouflage, biting and bulging to avoid predation. Both lizards (reptiles) and crickets (amphibians) have the ability to automatically disconnect, this is the spontaneous removal of the tail as a defense reaction. General defense is fake, and congenital defenseless animals protect the vivid colors of dangerous animals. For example, a harmless king snake might look like a toxic coral snake
