Harvesting Sea Turtle Eggs, Costa Rica

Of the seven species of sea turtles, all are listed on the IUCN Red List of Endangered Species as either "endangered" or "critically endangered". 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. While many of the things that endanger these hatchlings are natural, such as predators including sharks, raccoons, foxes, and seagulls, many new threats to the sea turtle species have recently arrived and increased with the ever-growing presence of humans.
Taxonomy and evolution
