The life cycle of a frog is a very interesting one. Right from the eggs to the final adult frog, it has some peculiarities. In the tadpole stage it resembles a fish and in no way resembles the frog it is going to be. If you have a frog in your aquarium tank, you can see each stage of the cycle and understand it easily. The requirements during each phase are different. Kids enjoy watching the tadpoles take shape into the adult frogs and the transformation.
The frog life cycle consists of three distinct stages – the eggs, tadpoles, and frog. The adult frogs lay the eggs either in water or at wet places. The eggs, unlike those of other creatures, are a clump of floating slippery objects. These are called as spawns. The bigger the clump, more are its chances of its survival. When small clumps float around, fishes and other aquatic animals can eat them easily. Each egg is protected by a jelly like coating. Initially the egg will be a single cell. In due course of time, it multiplies and form a group of cells called embryo. Gradually, all organs and the gills form. It remains in the development phase for 21 days.
In the tadpole phase, the embryo comes out of the jelly cover and gets itself attached to weeds in the water and transforms into a tadpole. The tadpole resembles a small fish as it will have a long tail. It feeds on the tiny plants and weeds in the water and grows. The dangers associated with this phase are being eaten up by other animals and the water getting dry leaving the tadpoles dead. After being in the tadpole phase for around five weeks, it develops hind and fore legs. The tails become shorter and the lungs develop. They start coming to the water surface to take in air.
Over a period of time, they start looking like frogs, lose the tail, shed the skin, and lungs become fully developed. Once it develops completely into an adult frog, it will live most often on the land. But will take swims also. These start eating flies, worms, and other insects. When it finds a mate, the female will lay the eggs in the water or wet surface and the male will then fertilize it.
Frog life cycle is easy to understand as it can happen in your own tanks. You can observe the emergence and development of each features and the whole transformation itself. Frog and tadpole kits also are available in the market, using which one can grow them at home. When grown at home, do a bit of research on what to provide for it to feed on during each stage and the conditions to be provided for its healthy growth into an adult.
The interesting factor in the frog life cycle is the appearance and disappearance of the tail, the development of the gills and the lungs, and the entire transformation of the tadpole into the frog.
