Branchial respiration occurs in
Special vascularised structures called gills (branchial respiration) are used by most of the aquatic arthropods (e.g., prawn) and molluscs (e.g., snail). Insects (e.g., locust) have a tracheal system for respiration. Lizards (reptile) perform pulmonary respiration. Respiration in earthworms takes places through the moist skin (cutaneous respiration).
