Question

Quizplus · Accepted Answer

Most adult mollusks have internal gills, which are located in the mantle cavity. This includes bivalves such as clams and oysters, as well as gastropods such as snails and slugs. External gills are typically found on larval or early developmental stages of aquatic animals, such as some fish and amphibians. Marine arthropods may have a variety of respiratory structures including gills, but many do not have external gills. Larval insects do not have gills at all, but instead use small air tubes called tracheae to breathe.
