frog life cycle

 

The life cycle of a frog consists of three stages: the egg, the larva, and the adult frog, and it passes through these stages through a process called metamorphosis.

 The frog is not the only animal that undergoes this transformation process, but all other amphibians go through it, and the hormones prolactin control, and thyroxine in the process.

 

Spring is the breeding season for frogs in areas with a temperate climate, while the breeding season is during the rainy season in areas with a tropical climate, and many species lay their eggs in calm waters among plants in clumps that tend to gather together, where the eggs can develop in safety Relative, and the female lays eggs, so that the male releases sperm on him; to fertilize it.

 

The adults leave the eggs in many species of frogs to grow without care of them, and in return the parents remain with the eggs to take care of them while they grow in a few species, and when the fertilized eggs mature, the yolk in each egg divides into more cells, and begins to take the shape of a tadpole or Abu Dhabi, and within a period ranging from one to three weeks, the egg is ready to hatch, and the young tadpole comes out of the egg.

 

The tadpole has rudimentary gills, a mouth, and a long tail, and it moves a little during the first week or two of hatching the egg, and it absorbs the remaining amount of yolk in the egg to provide nutrients that strengthen it to be able to swim alone, and as it grows, its hind legs begin to appear, and its body lengthens, Its food turns to larger plants and insects, and in the last stages the front legs appear, the tail shrinks, and the skin is formed over the gills.

 

The gills and tail disappear when the frog is 12 weeks old, reaches adulthood, and is ready to venture out to dry land and re-cycle.
