It is NOT the pig.

Apes and dolphins are the only two of the three who reccognize themselves in mirrors. They are self aware, the same as humans.

Apes and dolphins are both tool users/makers. Apes make more tools, and take longer, making more safisticated tools. Dolphins of course are limited by their body shape, and water enviroment.

Dolphins will rescue humans. Apes, for the most part, prefer to kill humans (and each other). Dolphins rarely attack and kill other dolphins. Exception of course being Orcas who eat larger sea mamals, like seals, whales, and other dolphins.

From everything I've read and studied about dolphins, and apes, I would choose dolphins as the more intelligent animal.

Apes are self aware, but they are very "yo-me." First and foremost for the ape, is its own self, and filling its stomach. Everything else is a very distant second, like exploring, and learning.

Dolphins are always interested in learning, exploring and playing. They will leave food, even when hungry, for a chance to learn, explore and play.

Therefor I would say the dolphin is the most intelligent.
