Mating among leatherback sea turtles is a fascinating process. It usually occurs in warmer waters where the adults come together. Males often engage in competitive displays, swimming alongside each other to catch the attention of females. These displays can be likened to a dance, with movements that show strength and agility.
When a female is receptive, she may select a mate based on these displays. After mating, the female will embark on the long journey back to her nesting beaches, which can be hundreds of miles away. This trek is risky, as it exposes her to various predators and human impact, such as boat traffic and pollution.
Nesting and Egg Development
Once the female reaches her chosen nesting site, she digs a pit in the sand using her flippers. This is where she will lay her eggs, which can range from 50 to 200 in a single nest. The eggs are approximately the size of a grapefruit, and the temperature of the nest determines the sex of the hatchlings—warmer sand typically produces more females.
After laying her eggs, the mother covers them with sand and returns to the ocean, leaving the eggs hidden. The development period for these eggs varies, usually taking about 60 days. During this time, the eggs are vulnerable to threats such as temperature fluctuations and predators like raccoons or birds.
Hatchling Survival Rates
Hatching is a perilous time for baby leatherbacks. The hatchlings must break free from their eggs and dig their way to the surface. Once they emerge, they face a myriad of dangers as they race to the ocean. Predators await, and even natural elements can pose a risk. Only a small fraction of the hatchlings make it to adulthood. In fact, estimates suggest that only 1 in 1,000 hatchlings survive to reach maturity.
