What is the characteristic of organisms in the Nekton category?

Organisms classified as Nekton are characterized by their ability to move independently of water currents. This means they have a capacity for active swimming, allowing them to navigate through water bodies effectively. Nekton includes a diverse range of aquatic animals such as fish, marine mammals, and some invertebrates that are not bound to the movement of water around them, unlike planktonic organisms which drift with currents. This ability to swim freely enables Nekton to pursue food, evade predators, and exploit various ecological niches within marine environments. This characteristic is significant when studying various ecosystems and the interactions among different organisms within those systems.
