What role do sea turtles play in marine ecosystems?

Sea turtles play a crucial role in marine ecosystems, particularly in the regulation of jellyfish populations. By feeding on jellyfish, sea turtles help control their numbers, which can prevent potential outbreaks that may lead to detrimental effects on the marine food web. Jellyfish, when in excessive numbers, can disrupt the balance of marine life, including competing with fish for food and affecting the health of coral reefs and other marine habitats.

The ecological balance is maintained partially by the predation habits of sea turtles, making them essential for maintaining healthy marine environments. Their grazing behaviors also influence the growth of seagrasses and other habitats, significantly contributing to the overall health of marine ecosystems.
