1 both are mammals
2 both swim in water
3 both give birth to live young
4 both have tails
LOL
They both have blow holes and both are aquatic mammals.
whales and dolphins both have fins, but dolphins are much smaller than whales
They are both mammals
analogous
There are many similarities and differences between a shark and a whale. The similarities is that have a similar streamlined body structure but the differences are many including sharks are fish while whales are mammals, sharks have a vertical tail structure while whales have a horizontal one among others.
The only similarities would be diet (plankton), size and they both live in the ocean. Some whales eat plankton, as do whale sharks. Some whales are close to the same size as whale sharks. Otherwise, whales are mammals, and whale sharks are fish.
whales and dolphins both have fins, but dolphins are much smaller than whales
Blue whales aren't related to bottlenose dolphins, they are simply two different sea mammals with some similarities.
Very little apart from their size, Dolphins and Whales belong to the same Genus of Mammals. http://42explore.com/whale.htm
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
They are both mammals
You can't! Dolphins are whales.
Whales and dolphins.
Nothing they are the same...
analogous
There are no whales that give birth to dolphins. Dolphins give birth to dolphins; whales give birth to whales.
Some small whales are called dolphins, but small whales are still whales.
No, dolphins and whales are dolphins and whales, members of the Order Cetacea. Only people are humans. Humans, like dolphins and whales, are mammals. But humans are members of the Primate Order.
