What does a dolphin say?

I thought a female dolphin main character would be good, but she has much more potential as a secondary.

So how does a dolphin think? I don't know, but definitely the dolphin would see things differently.

Some lines which show that this dolphin really has something special to say :-) (ha!)

“You humans swim in shallow waters”

“I am not a fish”

 “…two reasons why humans smile, either you made some money or you’re having fun, and I think that wasn’t the latter…”

"You never lose it, you know, not even after 20 million years of devolution.”

“I’m a dolphin. Knowledge is inbred.”

“No, I can’t (bring back a human). Swim up to the beach, have a look at one for yourself.”

“A degree? Is that a piece of paper?” 

 “Well, for me, swimming came with the package.”
