What role does the leatherback sea turtle play in its marine environment?

The leatherback sea turtle plays a crucial role in marine ecosystems as a predator and prey. By feeding primarily on jellyfish, they help maintain jellyfish populations, which can influence the health of marine food webs and ecosystems. Additionally, as they migrate across vast distances, they contribute to nutrient cycling in the ocean, aiding in the distribution of nutrients across different marine habitats. Their nesting activities also enhance coastal ecosystems, providing nutrients to beach environments.
