Reproductive habits The breeding process of sea turtles is fascinating. Usually, that time frame is more dependent on their size than on age. Males will come to the breeding grounds every year to try and mate with as many females as possible. Green sea turtles reach sexual maturity between 20-50 years of age. The age also varies dramatically across species; hawksbills can reach sexual maturity as early as three years, while green sea turtles can take up to 50 years. Mating takes place at the shallow shore line.
Owens and Gaëlle Blanvillain Grice Marine Laboratory, College of Charleston 205 Fort Johnson Road Charleston, SC 29412, USA Contact e-mail: OwensD@cofc.edu Abstract All seven extant species of sea turtles are considered endangered or threatened with extinction. A Mating Pair Of Pacific Green Sea Turtles The females have the chore of digging a nest using their back flippers.
They will bury their eggs in clutches. Sea turtles feature a diversity of colors in their shell including olive green, brown, yellow, orange, and black. Each clutch has an average of 135 eggs. The larger they get, the more likely they are to start mating. Green sea turtles return to the same beach to breed each season. Reproduction.
Green Sea Turtle Reproduction. A sea turtle lays eggs into a nest dug in the sand. Once a site is chosen, the turtle uses her hind flippers to dig a vase-shaped hole about two feet deep, and then lays her eggs.
In summer, an ancient reproductive ritual begins when the female leaves the sea and crawls ashore to dig a nest in the sand.
It all begins when they migrate thousands of miles to the breeding sites, to find a partner for mating.
Captive Reproduction of Sea Turtles: An Important Success Story David Wm. The present-day warmer temperatures of incubation for the developing turtle eggs are prompting further concern for the ultimate survival of the green sea turtles. Environmental conditions experienced by animals constrain their energy acquisition and its subsequent allocation to growth and reproduction, which ult…
Introduction from the sea; Cross-cutting issues . There are seven species of sea turtle: the green sea turtle, Hawksbill sea turtle, loggerhead sea turtle, olive ridley sea turtle, Kemp’s ridley sea turtle, leatherback sea turtle, and flatback sea turtle. For the Green Seat Turtle, mating won’t occur until they are 15 or more years of age. During the nesting season, females lay an average of 5 clutches of eggs with approximately two weeks between each nesting. She uses her rear flippers to dig the nest hole, then deposits 80 to 150 eggs that look a lot like Ping-Pong balls. The shield-shaped carapaces or shells of mature green turtles can grow to 3 feet long; the turtles weigh about 330 pounds. Environmental conditions experienced by animals constrain their energy acquisition and its subsequent allocation to growth and reproduction, which ult… Besides, their body design and the hard shell make them a difficult prey for some marine predators. Females typically breed once every two to three years. Egg laying is the only time that the green sea turtles ever leave the water. After maturing, females nest every 2-4 years on their natal beaches. Sea turtles are among the oldest creatures on Earth and have remained essentially unchanged for 110 million years. Males will return to the location where they were born to find a mate annually.
Every year, from about May to September, nesting female sea turtles emerge from the Gulf of Mexico to use the beaches of the Gulf Islands to lay their eggs.

Sea turtles have unique anatomic features that provide them with everything necessary to satisfy all their feeding, reproductive and social needs. Green sea turtles are an endangered species, primarily because of the loss of nesting and feeding sites as a result of habitat destruction and coastal development, as well as pollution and poaching. Once a male find a female candidate, the former courtship her by maintaining physical contact with the flippers or slightly biting the neck and the tail.
