dolphins and elephants are two of the main ones, I mean, look at some of the things theyve taught gorillas, monkeys, and other primates. Koko that was able to communicate in American sign language... Hell, check out Stella the Dog and BilliSpeaks (old house cat) on youtube... their owners are teaching them how to commuincate with them in english using buttons on the floor that when pressed, say an english word. one time Stella the Dog's "beach" button broke, and she had to figure out how to tell her owner she wanted to go to the beach, so she pushed the buttons "Stella" "Go" "Water" "Outside" to communicate that thought. a completely unique sentence for her... because the "Water" button had only ever been used to describe the water in her water bowl, the stuff she drinks, and somehow she made the connection that the water at the beach, though a bit different, is the same kind of thing as the water in her bowl.
