The telltale spouts that are shaped around the floor occur when whales expel heat air that satisfies colder air to the surface and condenses into modest water droplets. (Andrew Russell, Flickr) Equally baleen and toothed whales breathe via blowholes (the whale’s Model of nostrils). They are observed on the top of their head and hook up with their lungs. Since cetaceans only try to eat via their mouths, which isn't linked to their lungs, they can lessen the possibility of drowning from drinking water transferring into their lungs whilst taking in a food.
