Not many people know that the common garden frogs and toads come under special category called amphibians. They are called amphibians because they can live both on ground and inside water. They have a special set of lungs that assist respiration irrespective of the location of the animal. The term amphibian is so commonly used these days that any thing that relates to dual life inside water and on ground is referred to as amphibious. They are also called amphibians because there is involvement of water at one particular level in the life cycle of the animal. Let us examine these amphibians one by one.
The amphibians include the general garden frog, salamander, giant salamander, newt, Caecilians, South African Ghost frog, Dancing frog, Bull Frog, Dart Frog, Tree Frog and Gardenia Seychelles. All these animals lead a dual life. They spend more or less equal amount of their life cycle on water and land. For instance, it has been found that amphibians find it extremely difficult to survive in the absence of water. Even, the common garden frog is found in places where there is a lot of moisture. You can even find the garden frogs inside the water tank or fountain in the park or house garden. The frogs are fond of water for several reasons. Whenever they mate, the breeding takes place inside water. The frogs need water as the medium to lay their eggs. The initial phase of the newly born tad poles also known as younglings of frogs need water to sustain a living. These tadpoles contain a special set of gills using which they breathe while in water. Interestingly if the tadpoles are taken out of the water, they will not survive for long. Such is the bonding between the frog's life cycle and water.
After spending a larger part of their life inside water, the tadpoles transform into frogs. During this transformational period, these tad poles rely extensively on water for their food. They feed on a lot of microbial animals called planktons. It is said that a garden water tank is always clean in the presence of frogs. In the absence of water, frogs find it extremely difficult to breed. Some tree frogs, which live inside the jungles with little or no flowing water, have found an innovative way to breed. These frogs rely on the flower dew and tree sap for breeding. For instance, the frogs lay the eggs inside the dew collected flower in which the tadpoles become active once the egg hatches. The tad poles have very little space to move around. However, they continue to survive in such as small space. Unlike garden frogs, which lay eggs in thousands, the tree frogs lay only a few eggs. Since the absence of the ecosystem for breeding is poor when compared to that of the garden frog, the number of eggs laid is less.
Newts are some times tadpoles that fail to grow into the full size of a frog. Such conditions are very normal in the amphibian world. The limbless amphibians are also found in the fresh water.
