And these habitats where aquatic animals and plants live on are referred to as aquatic habitats. Aquatic habitats may be freshwater, marine, or brackish water.

Aquatic animals that can move freely using their fins or tentalces, and other locomotory organelles to propel themselves in an aquatic medium. Movements, such as diving and swimming, are examples of an aquatic locomotion.
