In biological context, the term aquatic is used to relate to water, as in aquatic animals, aquatic plants, aquatic environment, aquatic habitat, and aquatic locomotion.
Aquatic animals pertain to animals that live predominantly in different water forms, such as seas, oceans, rivers, lakes, ponds, etc. Examples of aquatic animals include fish, jellyfish, sharks, whales, octopus, barnacle, sea otters, crocodiles, crabs, dolphins, eels, rays, mussels, and so on. Aquatic plants, on the other hand, are plants found in those habitats, such as water hyacinth, water lettuce, water fern, duckweed, water lilies, and watergrass. 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. Organisms possess morphological and anatomical adaptations that enable them to live and thrive in aquatic habitats. 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.
