Hatching is the process where an egg breaks open, allowing a young animal to emerge. This is most commonly seen in birds, like chickens, but it also occurs in reptiles, such as turtles. Inside the egg, the developing embryo grows and prepares for life outside. When the time is right, the baby animal uses a special structure called an egg tooth to crack the shell. The hatching process is crucial for the survival of many species. For instance, sea turtles travel long distances to lay their eggs on sandy beaches, and after hatching, the tiny turtles instinctively head toward the ocean. This journey is vital for their growth and development.
