Whales and dolphins are mammals, ie they are warm blooded air breathing animals whose ancestors, many millions of years ago, were land dwelling, four legged, furry animals. They have a blowhole - a modified nostril - connected to their lungs to breathe with. Whales do not have gills for breathing, and must instead surface in order to breath air above sea level. Fish have scales. Whales and dolphins don’t have gills. I said that whales with baleen use that to get plankton and other whales don't need to filter as they eat large prey. 9. They must come up to the surface of the water to get air. Whales even give birth to live baby whales that will get milk from their mom for food. A friend mentioned something about whales and gills, to which I said "No, they're mammals." Narwhals can hold their breath for up to 25 minutes. no!

They have a blowhole - a modified nostril - connected to their lungs to breathe with. Do Narwhals Need to Breathe Air? Whales even have a little bit of hair on their smooth skin, usually on the top of their head. When you consider Whales have a body temperature similar to ours, and that many of them live in the high latitudes with water temps. In most cases, mammals have hair or fur, while fish never do. 10. There'd also seem to be no real pressure/advantage, since air-breathing whales, dolphins and so on are pretty successful top-of-their-food-chain creatures.
