Living Things: the Dolphin

Dolphins are one of the most intelligent marine mammals. They have a friendly form and play full character. I’m going to compare and contrast social groups, cooperation and the intelligence of dolphins in the wild and captivity.
Many people said that dolphins are extremely social creatures and actually seem to depend on this interaction while hunting, mating and defending themselves and their groups.

It means when dolphins are hunting, they will cooperate with others very well. But in the SeaWorld, the dolphins will be fed by people regularly.   So these dolphins don’t have to hunt food on their own. Instead, they only have to wait for the eating time or do tricks well to get the food as rewards.
Dolphins are very friendly, and they can get along well with people. Dolphins rescue and help humans.
