Which Animal Has the Largest Lungs?
The animal with the largest lungs in the world is the blue whale. In total, its lungs have a combined capacity of over 1,300 gallons of air.
Blue whales can be found throughout the world's oceans. In their habitat in the Antarctic, blue whales can grow to be up to 110 feet long and can weigh more than 200 tons.
The lungs of the blue whale are highly efficient and are able to pass up to 90 percent of the inhaled oxygen to the bloodstream. In stark contrast, the equivalent figure for human beings, on average, is a scant 15 percent.
