Aquatic and terrestrial arthropods
Name the organs or respiratory adaptations do aquatic and terrestrial arthropods correspondingly present?
Expert
In crustaceans, usual aquatic beings, there are richly vascularized gills which make contact with water and allow gas exchange. In terrestrial insects the respiration is tracheal and gases flow within small tubes which join the animal external surface and ramify to tissues and cells with no the participation of blood. In arachnids, besides the tracheal respiration, book lungs (that is, thin folds like leaves in a book) might also exist.
