The diagram given illustrates the life cycle of sea turtles and the way in which they develop from eggs to adulthood and return to the sea to reproduce.
Looking at the illustration, it is immediately evident that this is a natural cyclical process that requires different environmental conditions at each stage. Additionally, there are several main stages involved in the process, beginning with egg incubation on beaches and culminating in adult turtles returning to the ocean after mating.
In the first step, eggs are placed in nests on sandy beach and incubated for about 8-10 weeks, after which hatchlings emerge and make their way to the sea. Following this, they enter a period called the “lost years,” lasting from 5 to 20 years, during which they forage on the surface of the open ocean. Then they undergo developmental migration for 30-50 years before reaching coastal shallow waters for foraging.
Once this stage has been completed, turtles grow into mature adults, ready for reproduction. In the next stage, adults migrate to shallow-water mating areas, where mating takes place at two-week intervals. Adult males return to the foraging areas, while adult females go back to the nesting beaches to lay eggs, thereby continuing the process.
