What do whales and dolphins Breathe through?
Whales and Dolphins Breathe through blowholes, modified nostrils on top of their heads.
Fish,whales dolphins etc. have gills. The simple REAL answer to this is they have gill's and the only animals that live underwater are fishes,dolphins whales etc. EDIT: This is simply false. Whales and Dolphins do not have gills. They are mamals, with lungs, and must come to the surface and breathe air.
Whales started out as land living mammals - some still have remains of hind legs in their bodies - which eventually somehow turned into sea-living mammals. And while many parts of their bodies changed to fit a swimming lifestyle, they still breathe air, with lungs. If whales and dolphins did not come up to the surface to breathe, they would drown and there would not be any dolphins or whales!!
Similarities: * Whales, dolphins and fish are all vertebrates * They all need to live in water and cannot survive out of water for long * They all have a streamlined body shape, with dorsal and pectoral fins Differences: * Whales and dolphins are mammals, but fish are simply classified as "fish" * Fish have scales (even a shark has fine scales); whales and dolphins have smooth skin * Fish breathe through gills; whales and…
Sharks and whales are actually not related to each other. A shark is a type of fish. They breathe through gills, and do not nurse their pups. Whales are mammals. They are warm blooded, breathe surface air, and nurse their calves. The animal that is probably the closest relation to the whale would be a dolphin. Certain types of dolphins, such as orcas, are often mistaken for whales.
