The nesting sea turtle female hauls herself onto the beach, nearly always at night, and finds suitable sand on which to create a nest. Using sea turtle`s hind flippers, sea turtle female digs a circular hole 40 to 50 centimetres (16 to 20 in) deep. the sea turtle female then starts filling the nest with a clutch of soft-shelled eggs one by one until sea turtle female has deposited around 50 to 200 eggs, depending on the species. Some species have been reported to lay 250 eggs, such as the hawksbill. After laying, sea turtle female re-fills the nest with sand, re-sculpting and smoothing the surface until it is relatively undetectable visually. The whole process takes thirty to sixty minutes. sea turtle female then returns to the ocean, leaving the eggs untended.

The BABY SEA TURTLE's gender depends on the sand temperature. Lighter sands maintain higher temperatures, which decreases incubation time and results in more Baby sea turtle females.
Incubation takes about two months. The eggs in one nest hatch together over a very short period of time. When ready, BABY SEA TURTLEs tear their shells apart with their snout and dig through the sand. Again, this usually takes place at night. Once they reach the surface, they instinctively head towards the sea. If, as happens on rare occasions, hatching takes place during daylight, only a very small proportion of each BABY SEA TURTLE succeed (usually 1%), because local predators, such as the common seagull, gorge on the new sea turtles. Thus there is an obvious evolutionary drive to hatch at night, when survival rates on the beach are much higher.

The BABY SEA TURTLEs then proceed into the ocean, where a variety of marine predators await them. the BABY SEA TURTLEs spent a great deal of their pelagic lives in floating sargassum beds, where there are thick mats of unanchored seaweed. Within these beds, they found ample shelter and food. In the absence of sargassum beds, sea turtle young feed in the vicinity of upwelling "fronts".
