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 dolphins use lungs and a blowhole, which really functions like a nose, on top of their heads * Most fish lay eggs, while whales and dolphins give birth to live young * Fish are cold blooded; whales and dolphins are warm-blooded * Swimming motions are different: Fish moves through the water by using their body muscles to push their tails side-to-side; whales and dolphins move by pushing their tails up and down
