Noise pollution from ship engines and industrial activities can disrupt their complex communication and interfere with their ability to locate the surface. They have two lungs located along their dorsal cavity, connected to a blowhole situated on the top of their heads.
How Whales Manage Air Interaction at the Surface
Threats to Respiratory Function The very act of breathing at the surface exposes whales to significant anthropogenic threats. Air expelled from the blowhole at speeds reaching 300 miles per hour creates a visible mist or spray, known as the blow.
The shape and height of this blow are species-specific; a right whale’s V-shaped blow differs dramatically from the columnar spray of a blue whale. Furthermore, chemical pollution and plastic debris pose direct risks to their respiratory health; ingesting or inhaling these toxins can lead to severe health complications, compromising their ability to breathe air effectively and undermining the delicate balance of their marine ecosystem.
How Whales Interact with Air for Survival
Furthermore, their blood and muscle tissues contain high concentrations of myoglobin, a protein that stores oxygen, allowing them to undertake deep, long-duration dives lasting up to two hours. While humans breathe automatically, whales must actively decide to breathe.
