Pelagic fish are species that live in the open ocean, away from the bottom and coastal areas. They are often found in the upper layers of the water, where they can easily swim and hunt for food. Common examples of pelagic fish include tuna, mackerel, and sardines. These fish are known for their streamlined bodies, which help them swim quickly through the water. These fish play a crucial role in marine ecosystems, serving as both predators and prey. They feed on smaller fish, plankton, and other marine organisms, while also being a food source for larger animals like sharks and dolphins. Pelagic fish are important for commercial fishing and are enjoyed by many as a source of healthy protein.
