Frogs :: essays research papers

Frogs are amphibians in the order Anura. The order Anura is broken cumulation into 22 different families of captures and toads. Although they belong to the same order, frogs and toads are different in a lot of ways. nearly of the more distinct differences are their cutis and where they resilient. Frogs usually consume smooth moist skin and toads usually have dry weeweey looking skin. Frogs spend most of their passs in or near water and toads spend more time on land. amphibious means "double life." Frogs and toads each have two parts to their lives when they live on water and when they live land. A frogs life starts in the water when it is hatched from an egg as a tadpole. A tadpole looks actually different from an adult frog. A tadpole has a tail, no limbs, and breathes through with(predicate) gills. After a while the tadpole goes through metamorphosis. During the change the frog grows limbs, the tail disappears, it uses lungs to breathe, and it doesnt have to li ve in water anymore. As a tadpole, the frog feeds mostly on vegetation. The tadpoles have a small spotty mouth suited especially for scraping algea from the bottom of pocket billiardss. Depending on the species, it kitty take a few weeks to a year or more for the tadpoles to become fully grown. Not all frogs hatch as tadpoles. Some species of frogs hatch as froglets. Froglets look just like adult frogs alone are a lot smaller. Froglets dont go through a metamophosis. virtually species that hatch as froglets are found in dry places. Frogs who live in dry places where rains are seasonal have to grow up quickly because a tadpole will die if their temporary pond dries up. Adult frogs can live in water or on land, but it always needs to be near water so its respiratory organs dont dry out.
