Everything from footprints to driftwood and crabs are obstacles, though this gauntlet is important for its survival. Birds, raccoons, and fish are just a few of the predators these vulnerable creatures face; some experts say only one out of a thousand will survive to adulthood under natural conditions.
After an adult female sea turtle nests, she returns to the sea, leaving her nest and the eggs within it to develop on their own. The amount of time the egg takes to hatch varies among the different species and is influenced by environmental conditions such as the temperature of the sand. The hatchlings do not have sex chromosomes so their gender is determined by the temperature within the nest. Whether hatchlings are male or female depends on the temperature where they are in the nest, known as the “pivotal temperature." The temperature varies slightly among species, ranging between roughly 83-85 degrees Fahrenheit (28-29 degrees Celsius), at which embryos within a nest develop into a mix of males and females. Temperatures above this range produce females and colder temperatures produce males.
After 45 to 70 days (depending on the species), the hatchlings begin to pip, or break out of their eggs, using a small temporary tooth located on their snout called a caruncle. Once out of their eggs, they will remain in the nest for a number of days. During this time they will absorb their yolk, which is attached by an umbilical to their abdomen. This yolk will provide them the much-needed energy for their first few days while they make their way from the nest to offshore waters. #leatherback #turtle #caboverde #santaluzia #seashepherd #sealegacy #turningthetide
