How do dolphins leap so high out of the water?

They seem extremely capable of jumping great heights too, almost as if there is some evolutionary purpose.

As a bonus question if I may, WHY do they jump out of the water?

It's just a function of being able to swim fast.

Compare it to the ability to jump high by NFL tryouts.

They don't need the ability to hump high per se, but it comes with training for high speed running.

They even can jump higher than NBA players...
