Explain The Respiratory System Among Different Animals?

Respiration is mainly of two types that are aerobic and anaerobic. Aerobic respiration includes cutaneous, branchial and body surface respiration. Aerobic animals require oxygen which is utilized from air or water. Organisms like Hydra show body surface respiration. These are aquatic animals. Animals like fishes, prawns have gills for respiration. This phenomenon is known as branchial respiration. They help in the exchange of gases. Certain animals such as earthworm, leech etc. exchange gases by skin and this phenomenon is known as a cutaneous respiration. Some organisms like insects show tracheal respiration in which the exchange of gases occurs by the presence of tubular structures known as trachea. Organisms like arachnids have book lungs which exchange gases by lungs. Book gills are present in king crabs. Lungs are the organs for the exchange of gases in pulmonary respiration. In some organisms exchange of gases takes place in the epithelial lining of bucco pharyngeal cavity and is known as bucco pharyngeal respiration. Frogs and toads have these types of respiration. Anaerobic organisms do not require oxygen for survival. They are mainly of parasitic type.
