Do you know that the dolphin is the most intelligent animal in the world?
Yes. Dolphins have a big brain and they are very smart. They are also the fastest swimmers in the world.
They must be amazing animals.
They are. I read a story about a dolphin saving a A from drowning in the sea.
I read that story too. They seem to be able to understand men.
They sure can. Maybe they can interact with men better than monkeys and apes.
