Most sea turtle mortality happens early in life. Sea turtles usually lay around 100 eggs at a time, but on average only one of the eggs from the nest will survive to adulthood. [135] Raccoons, foxes, and seabirds may raid nests or hatchlings may be eaten within minutes of hatching as they make their initial run for the ocean. [136]
The loggerhead sea turtle has a low reproductive rate; females lay an average of four egg clutches and then become quiescent, producing no eggs for two to three years. The loggerhead reaches sexual maturity within 17–33 years and has a lifespan of 47–67 years.
In contrast to their earth-bound relatives, tortoises, sea turtles do not have the ability to retract their heads into their shells. Their plastron, which is the bony plate making up the underside of a turtle or tortoise's shell, is comparably more reduced from other turtle species and is connected to the top part of the shell by ligaments without a hinge separating the pectoral and abdominal ...
A mean clutch size of 116 (30–168 eggs) was observed in Suriname, while nesting females from the eastern Pacific were found to have an average of 105 (74–126 eggs). [11] The incubation period is usually between 45 and 51 days under natural conditions, but may extend to 70 days in poor weather conditions.
Since 1999, the Florida Aquarium has led extensive sea turtle rehabilitation efforts and visitor and community education & conservation platforms to advance sea turtle protection. Over a 20-year period, the aquarium received 200 sea turtles, and while not all could be released due to the nature of their injuries or illnesses, 180 were ...

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.
A flatback sea turtle hatchling is larger than other sea turtle hatchlings with its carapace length averaging 60 mm (2.4 in). [6] Its large size helps protect it from some of the predators after hatching, and allows it to also be a stronger swimmer. [6] The hatchlings tend to stay close to shore and lack the pelagic phase of other sea turtles.
