Aquatic arthropods respire through:
Correct answer: B. Gills
- A. Lungs
- B. Gills
- C. Skins
- D. Spiracles
Explanation
Aquatic arthropods respire through gills. Gills are specialized respiratory organs that allow these arthropods, such as crustaceans (e.g., crabs, lobsters, shrimp) and some insects (e.g., aquatic beetles), to extract dissolved oxygen from water and release carbon dioxide.Gills are typically thin and highly vascularized structures that provide a large surface area for efficient gas exchange. As water flows over the gills, oxygen diffuses from the water into the blood vessels in the gills, while carbon dioxide from the blood diffuses into the water and is released.
