Tadpoles live in water, as they develop they grow legs and lungs which then allow the to live on land, as adult amphibians.
At birth, a tadpole is essentially a head with eyes and a tail. Many internal changes must occur before a tadpole is ready to be a land dwelling frog. As a tadpole grows, she will develop bones. The tadpole must also grow some new internal organs, the most important of which are the lungs, and a fully grown heart.
The first difference is that a tadpole (after being hatched) has gills because its body has not developed enough muscular structure to survive on land, so it live underwater, the frog however breaths through lungs (mature frogs cannot breath underwater). Second, a tadpole has a tail, while a frog is tailless. Third, a tadpole does not have any legs (until later in life) while a frog has very long hind legs for leaping.
It doesn't.
Large numbers of numbers cannot survive on land covered with Ice, Deserts, or high Mountains.
Every creature's shape has evolved to help it survive in one way or another.
A Tadpole, the larval form of a frog. Sometimes also referred to as a "wollywog" or "pollywog".
because it hasn't developed lungs yet
aquatic plants live in water because they cannot survive on land
Plants survive in land by the water
Triops may try to go on land, but they cannot survive for long. They can only breathe underwater and they will dry up without water.
Was in water. And is now on land. Ex: a frog. A tadpole live in the water first. Then it grows and lives on land.
Egg is to tadpole as tadpole is to frog.
