Answer 2

Many aquatic species, including worms, virtually all mollusks and crustaceans, certain insect larvae, all fishes, and a few amphibians, have gills.

• The gill is made up of branching or feathery tissue that is densely packed with blood vessels, particularly at the gill surface, allowing oxygen and carbon dioxide to be exchanged with the surrounding water.
• The gills may be encased in chambers through which water is forced forcibly, or they may extend into the water from the body.
