What does amphibian mean?

"Amphibians" refer to a class of vertebrate animals that live in alternating environments between water and land. They usually have two different lifestyles: aquatic and terrestrial. These animals have special physiological structures and behavioral adaptations that allow them to move freely in water and on land. Amphibians, for example, typically have limbs, organs such as gills and lungs, as well as mechanisms to regulate their body temperature and breathing patterns.

Amphibians include hundreds of different species such as frogs, salamanders, salamanders, and salamanders. They are widely distributed around the world, from tropical rainforests to boreal swamps. Amphibians play an important role in nature. They not only play an important role in maintaining ecological balance, but also make important contributions to human scientific research and the development of life sciences.
