Many multicellular animals do not require oxygen to live but respire anaerobically. Some of these have adapted to hostile environments, such as sulphide rich habitats, others live as parasites within host organisms, while others still can perhaps be said to look back on the early days of life on earth before anaerobic respiration had evolved.
