Water spraying is a beautiful feature of whales. Why do they spray water? First of all, they certainly don't spray water because they have a cold or a runny nose! We know that whales are mammals, breathe with their lungs, and like humans, they must inhale oxygen and exhale carbon dioxide, so they must exchange gas on the water. Early whalers thought whales were spraying water. Actually, it's steam exhaled by whales. It consists of exhausted gas and condensed water vapor, and of course it also contains some internal emulsion, mucus or some body fluids to help them breathe. Breathe in after a strong exhalation, and then pause briefly before circulation, often breathing 5 or 6 times a minute until the whale dives into the sea. Whale spray has different characteristics according to different climate seasons and different species sizes. In cold weather, the jet stream is more obvious, but it will be blown away in strong winds. We know that the esophagus and trachea of many mammals are clear. If our nostrils are blocked, we can still breathe through our mouths. If we accidentally choke on water, we will instinctively shoot water by coughing. Once a whale's nostrils are blocked, it is in danger of suffocation. Once a whale was hunting flounder, and the escaped flounder got into the whale's breathing hole, causing the whale to suffocate and die.
