The epipelagic zone, also known as the sunlight zone, is the top layer of the ocean that extends from the surface down to about 200 meters (656 feet). This zone is rich in sunlight, allowing photosynthesis to occur, which supports a diverse range of marine life.
Inhabitants of the epipelagic zone include a variety of fish species such as sardines, mackerel, and tuna, which are known for their agility and speed. Additionally, larger predators such as sharks and dolphins thrive in this region, hunting smaller fish and keeping the ecosystem balanced.
Besides fish, many types of marine mammals, like whales, and various species of jellyfish can also be found here. Sea turtles are common visitors as they often forage in these productive waters. Moreover, plankton, both phytoplankton and zooplankton, serve as the foundation of the food web, making them crucial for the survival of many organisms in this layer.
Overall, the epipelagic zone is teeming with life, reflecting the abundance of nutrients and light available, making it a vital area for marine biodiversity.
