Depending on the species, the number of eggs laid varies from one to over 100. Larger females can lay eggs that are greater in number or bigger in size. Compared to freshwater turtles, tortoises deposit fewer but larger eggs. Females can lay multiple clutches throughout a season, particularly in species that experience unpredictable monsoons. [94]
Like all turtles, map turtles are oviparous, typically laying eggs from late June to August. Females lay two to fifteen eggs per clutch and, depending on a number of variables such as species, size, and age, among other factors, may skip a year between clutches, or lay as many four clutches a year.

Sea turtle eggs sold in a market of Malaysia. Another major threat to sea turtles is the black-market trade in eggs and meat. This is a problem throughout the world, but especially a concern in China, the Philippines, India, Indonesia and the coastal nations of Latin America.
Typically large numbers of eggs are laid at one time (an adult female cod can produce 4–6 million eggs in one spawning) and the eggs are then left to develop without parental care. When the larvae hatch from the egg, they often carry the remains of the yolk in a yolk sac which continues to nourish the larvae for a few days as they learn how ...
The mean number of eggs in a clutch varied from 2.67 to 3.55, there was no indication of multiple clutches being produced, and variation in egg numbers was only weakly explained by the cloaca of the female. Clutch size was positively correlated with the maternal body size, but egg width was not related to the maternal body size but was related ...
About 50% of female sea turtles complete "false crawls," which occur when they crawl onto the beach but return to the water without laying eggs.
Graciela Tiburcio, a biologist and sea turtle expert, told the AP that moving the eggs would cause many to die — but the number would be higher if they did nothing.
The homing characteristics of the ridley sea turtles make them more prone to mass casualty. The voyage to the natal nesting beaches is the dooming factor for them. Since Gahirmatha coast serves as the natal nesting beach for millions of turtles, it has immense importance on turtle conservation.
