Nekton

Nekton are aquatic animals that can actively swim and move independently of water currents, such as fish, whales, and squid. Unlike plankton, which drift passively, nekton have strong muscles and fins or limbs enabling them to navigate through the water in search of food, mates, or habitats. They play a vital role in marine ecosystems by maintaining the food chain and contributing to ocean biodiversity. Nekton can inhabit various depths, from shallow coastal waters to the deep ocean, and their ability to move effectively is essential for their survival and ecological function.
