During the breeding season, females will come to the beach to lay their eggs, while males never leave the ocean. Hatchlings are the first stage of a turtle’s life. They are about the size of an egg, and are covered in a soft shell. The shell is made up of calcium carbonate, which is found in the shells of many marine animals. When the shell hardens, the hatchling will grow into a full-grown adult.

Do green sea turtles live in coral reefs?
According to the first comprehensive in-water survey of turtle populations in the world, the number of green turtles in pacific coral reefs is increasing. The survey, conducted by the International Union for Conservation of Nature and Natural Resources (IUCN) and the University of Hawaii at Manoa, found that the number of green turtle species has increased by more than 50 percent over the past 30 years.
The study, published in Conservation Biology, is the most comprehensive to date of the turtle’s distribution, habitat, and abundance. It is also the largest study of its kind, encompassing the entire world’s oceans, including the Caribbean, Indian and Pacific Oceans, as well as the Atlantic, Gulf of Mexico, Pacific and Indian oceans. “This is a very exciting time for turtles,” said study co-author and UH Mānoa professor of ecology and evolutionary biology, Dr. David R. Williams.
“We are seeing a dramatic increase in turtle abundance, which is good news for the future of our oceans and for our planet.” , the study’s lead author, said, “Turtles are a keystone species that play an important role in maintaining the health and diversity of marine ecosystems.
What oceans do sea turtles live in?
Sea turtles are found in all of the world’s oceans except for theAntarctica. Sea turtle eggs are laid on the ocean floor and hatch in a matter of weeks. The hatchlings grow rapidly, reaching a length of up to 2.5 feet (0.9 meters) and a weight of more than 100 pounds (45 kilograms). By the time they reach adulthood, the sea turtle can weigh as much as 1,000 pounds.
How many green turtles are left?
Small turtles are sometimes stuffed for curios and other green turtle parts are used for leather. An increasing source of mortality is the incidence of catch in commercial shrimp trawling.
Where does turtle live land or water?
Turtles inhabit water bodies (both fresh and sea water), are smaller in size and their life spans are lower than tortoises’. They have flippers that make it easier to swim. Carapace is flatter than their shells. Scales give them a more reptilian appearance. They are found in tropical and subtropical regions of the world, including the Americas, Africa, Asia, Australia, New Zealand, South America, Europe, North America and Oceania.
Why do green sea turtles go on the beach?
Why do green sea turtles bask on land? Sea turtles are ectothermic, meaning they rely on the environment to regulate their body temperature. It’s a way to raise their body temperature, rest, escape potential predators, and improve their immune systems. They are related to lizards, snakes, turtles and tortoises.

What kills green sea turtles?
Bycatch in commercial and recreational fishing gear, vessel strikes, loss of nesting habitat from coastal development, and climate change are the biggest threats to the species’ survival.
“This is the first time we’ve seen a species go extinct in such a short period of time,” said study co-author and University of California, Santa Barbara, professor of ecology, evolutionary biology and marine biology, David R. Smith.
“It’s a very, very sad story, but it’s also a reminder that we need to do everything we can to protect this species.” the study was published in the journal Proceedings of the National Academy of Sciences.
