Complex animals, often referred to as multicellular organisms, exhibit intricate structures and functions that result from the specialization of cells into tissues and organs. This level of complexity allows for advanced physiological processes, such as respiration, circulation, and nervous system functions. Examples include mammals, birds, reptiles, amphibians, and fish, which possess systems that enable them to interact with their environment in sophisticated ways. Their complexity contrasts with simpler life forms, such as unicellular organisms or sponges, which lack organized tissues and systems.
