The development of the eggs is dependent on the temperature of the environment that they were buried in, with warmer climates bringing about an earlier emergence by the hatchlings. The timing of sea turtle hatching tends to be almost synchronous among the whole clutch of eggs, with just about all the eggs in the nest hatching within the same time.
The hawksbill turtle are one of the few animals known to feed primarily on sponges. It is the only known spongivorous reptile. [1] Sponges of various select species constitute up to 95% of the diets of Caribbean hawksbill turtle populations. [2]
Throughout the world, hawksbill turtles have been hunted by humans, though it is illegal to capture, kill, and trade hawksbills in many countries today. [3] [58] In some parts of the world, hawksbill turtles and their eggs continue to be exploited as food.
2) Sea turtles mate in the water near offshore nesting sites. 3) The adult male sea turtles return to the feeding sites in the water. 4) Female sea turtles cycle between mating and nesting. 5) Female sea turtles lay their eggs. 6) When the season is over, female sea turtles return to feeding sites.
Sea turtles are largely solitary animals, though some do form large, though often loosely connected groups during nesting season. Although only seven turtle species are truly marine, many more dwell in brackish waters. [1] [6] Sea snakes: the most abundant of the marine reptiles, there are over 60 different species of sea snakes.
Many turtles from the same beaches show up at the same feeding areas. Once reaching sexual maturity in the Atlantic Oceans, the female Loggerhead makes the long trip back to her natal beach to lay her eggs. The Loggerhead sea turtle in the North Atlantic cover more than 9,000 miles round trip to lay eggs on the North American shore.
Green sea turtles and hawksbill sea turtles shuttle between fixed foraging and nesting sites. Both species of ridley sea turtle nest in large aggregations, arribadas. [17] This is thought to be an anti-predator adaptation — there are simply too many eggs for the predators to consume. One unifying aspect of sea turtle migrations is their ...
Although sea turtles usually lay around one hundred eggs at a time, on average only one of the eggs from the nest will survive to adulthood. [2] While many of the things that endanger these hatchlings are natural, such as predators including sharks, raccoons, foxes, and seagulls, [3] many new threats to the sea turtle species are anthropogenic.
