Which one of the following organs is the main respiratory organ of whale?
- a.Integuments
- b.Gills
- c.Lungs
- d.Trachea
Answer: (C) Lungs
Whales, dolphins and porpoises are mammals (order Cetacea), so they breathe air with lungs through a blowhole on the top of the head and must come to the surface to breathe. Gills are the respiratory organs of fishes, the moist skin (integument) is used by earthworms and frogs, and tracheae by insects. The blue whale is the largest animal; whales are warm-blooded and suckle their young.
