Throughout their lifecyle, and in their critical habitats, sea turtles face several obstacles for their survival.
Predators such as birds, raccoons, mangooses, crabs and ants can predate on their eggs or the hatchlings in the nest, or once they emerge on the sand surface. Once these hatchlings start their crawl towards the sea, they are vulnerable to many other predators.
Once sea turtles reach sexual maturity, they are almost immune to predation, and the only danger they might face is the occasional attack by sharks and killer whales. It is only during the nesting season that sea turtles become very vulnerable to human or animal predation.
Nevertheless, there are many other threats other than natural predators that might endanger the survival of the species. In order to truly understand the factors which pose a threat to this species it is important to reduce the anthropogenic threats.
