If you’ve ever watched whales surfacing with a dramatic blow from their blowholes, you’ve most likely wondered: How often do whales come up for air? In brief, it relies on the species, their exercise and the way deep they dive. Whales are marine mammals, not fish, and they absolutely should breathe air. Whales don’t have gills, so they can’t breathe underwater. These marine mammals have lungs similar to humans and need oxygen to survive. They inhale and exhale by a blowhole on high of their heads, making it easier to breathe while swimming close to the ocean surface. When whales exhale, they release a spout of air and water vapor - sometimes with a bit of mucus - which will be seen from far away. Their blood accommodates more hemoglobin and myoglobin than people, which permits them to store a lot oxygen. When taking a deep breath, whales can substitute as much as ninety p.c of the air of their lungs, in comparison with 10 to 15 % in humans.
