Animals can be classified into four main categories based on their movements: sessile, sedentary, migratory, and nomadic.- Sessile animals are immobile and permanently attached to a surface, such as barnacles or corals.- Sedentary animals have limited mobility and usually stay in one place, but they can move short distances if necessary. Examples include sea anemones and sponges.- Migratory animals move seasonally from one location to another in search of food, breeding grounds, or better environmental conditions. Birds and certain mammals, like wildebeests, are well-known migratory species.- Nomadic animals constantly move in search of food and water sources. This includes animals like herds of grazing animals, such as zebras and bison.
