The provided diagram illustrates the life cycle of a frog, tracing from its development as eggs to a fully grown adult.
Overall, the continuous cycle reveals 7 distinct stages of more than a 12 week period, during which the creature transforms from an aquatic egg into an animal capable of living on both land and water.
To begin, the frog is born through a stage called, “Frog Spawn”, before hatching into new tadpoles. During this stage, the tadpole begins to grow noticeably larger as weeks pass by. After the sixth week, it forms a relatively large head shape, while its external gills completely disappear.
Following this, during the 8th week, the tadpole begins to evolve hind legs gradually. Consequently, through the 12th week stage, its front legs are formed, while its tail shrinks. By the end, the tadpole begins to mature into a fully developed frog. Furthermore, with its tail almost gone, the frog can now hop out of the water onto land, as well as move freely on both spaces.
