Amphibians Breathe Through In Water

Frogs are amphibians and not fully aquatic animals they still breathe through.

Amphibians breathe through in water. Amphibians also have special skin glands that produce useful proteins. Some amphibians can hold their breath for hours. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist If they get too dry they cannot breathe and will die.

With some amphibians it appears that they can breathe underwater when in fact they are holding their breath. Due to their gill-breathing stage they must however be close to water or even primarily live. Tailless amphibians move in water by pushing their powerful webbed hind legs through the water.

This is important for two reasons. But as a baby amphibian grows up it undergoes metamorphosis a dramatic body change. With the exception of a few frog species that lay eggs on land all amphibians begin life as completely aquatic larvae.

Every organism requires a specialized organ to breathe for example humans have lungs fishes have gills earthworms have skin for breathing. They live the first part of their lives in the water and the last part on the land. Air passes through their nostrils the trachea and the glottis and is then divided to each bronchi and received by the lungs.

When they get older they start to breathe through their lungs which allows them to live on land. Tadpoles breathe in water and force it past their external gills in the beginning so that tiny blood vessels in their gills can absorb the oxygen in water and put it directly into the blood stream. They also have fins to help them swim just like fish.

Amphibians are a class of animals like reptiles mammals and birds. Not all amphibians can breathe underwater. When frogs are tadpoles they breathe underwater through their internal gills and their skin.
