The lung capacity of whales varies with each species. Blue whales are the largest species of whale and have a lung capacity of 5,000 litres or about 1320 gallons. A blue whale’s lungs are connected to its twin blowholes (see below image). The blow (the exhaled air and vapor) can go up to 20 feet high! The blue whale breaths
It depends on the whale. The blue whale, the largest of all whales, has a lung capacity of 5,000 liters (1320 U.S. gallons), while the dwarf sperm whale (the smallest whale) has a lung capacity only slightly larger than a human’s. There is a general pattern to the capacity of the lungs in a mammal: the volume in ml is roughly equal to 56.7 times the mass of the mammal (in kg).
In relative terms, a blue whale’s lungs are about the size of a small to mid-sized car. In comparison to their total body masses, however, whales’ lungs (in general) are relatively small. The humpaback whale’s lungs, for example, account for only 1-3% of its total body mass, whereas a human’s lungs account for 7%.
