Aug 26, 2021 · The location of their “nose”, the blowhole, on the top of their head allows them to exchange breathing air efficiently during the sometimes brief surfacing. But how does the blowhole of whales and dolphins actually get on top of the head?
As whales reach the water surface to breathe, they forcefully expel air through the blowhole. The exhalation is released into the comparably lower-pressure, colder atmosphere, and any water vapor condenses.
Feb 6, 2012 · The whales were coaxed from breathing hole to breathing hole, slowly moving out toward the open ocean. Operation Breakthrough. On the other side of the frozen ice, a Soviet icebreaker...
Sep 22, 2020 · This is how water and pollutants can enter the animals’ respiratory tracts, scientists conclude. A humpback whale spouts water from its blowhole. New research shows the blowhole isn’t as protective as scientists had thought, and water and pollutants may be getting into whales’ lungs.
For whales, breathing through nostrils sited in the customary position on the front of the face would be highly inefficient as it would require lifting the head up out of the water. Which is why cetacean nostrils have migrated to the top of the head to become blowholes.
Aug 5, 2021 · Fin whales are from a group called the baleen whales, named for their distinct feeding apparatus. “I’m struck by two interesting discoveries that emerged from this work,” said Roth. “Although they both develop blowholes, there are key differences between a baleen and a toothed whale in how they reorient their nasal passages during ...

Whales cannot breathe through their mouth because, unlike terrestrial mammals, their digestive system and respiratory system are not connected. The blowhole leads to the nasopharynx, or nasal duct.
