Without *** doubt, the train dolphin show is one of the premier attractions here at marine world. But what's happening behind the scenes with these friendly mammals, you may find more exciting and fascinating than any tricks they could ever perform. I find that some days I, I kind of look at them in amazement and think. Oh, this is incredible. And other days, I just II I feel that why aren't they getting this? I, I don't, I simply don't have *** real feeling for what their level of intelligence is. I don't even know what the appropriate metric would be to measure it yet. That's one of the things I'm I'm interested in working on the dolphin is the most elaborate creature in the sea. But even with his large brain and acoustic range finding and object detecting system, no one knows just how high in IQ he has. And that's what keeps researchers like Diana Reiss working seven days *** week in search of clues. I'm not interested in language, developing language, *** human system of language. I'm interested in looking at the way two species that are very different physically and from different environments can merge their patterns of behavior and function in something that function with something that looks like communicative behavior where one species can affect the changes in behavior of another species. And this is how the San Francisco State professor is trying to communicate with these aqua animals with the keyboard of symbols that *** dolphin can push to get what he wants. Hey, circle. And we see an open mouth here and he gets *** fish for that one. And we're offering balls if they touch the triangle, if they touch the cross, they get hoops if they touch the circle fish and if they touch an H shape, they get *** rub down from us. But dolphins intelligent as they might be, don't always want to, but she's not even making eye contact right now. She's heading for bordeaux and she's rubbing on Gordo's pec fin. So that's probably what she's most interested in. Ok. Ok. Let's try free choice with bordeaux. Yes. Intelligent as these dolphins might be during mating season. Pushing buttons takes *** back seat to play. At least for the females. They tend to cut themselves back *** lot during sexual seasons. And um, we don't force them if they don't want to eat. That's their prerogative and that's the end of it. But besides working with Cymbals, Diana and her crew also work with Marine World's chief trainer observing the dolphins during performances to learn more about behavior and while the mammals are performing for crowds. These researchers are taping the action and recording the sound from an underground. And as chief dolphin trainer, Jim Mullen surprisingly discovered Diana's research has uncovered some astounding dolphin behavior. For example, when he gives commands for *** group trick, one dolphin takes command on team behaviors where it takes more than one animal. Usually you have *** leader or someone who's shouting the the commands to do certain movements or follow me whatever the case may be. So, it was our intention to find out who exactly was giving those commands on any given behavior. But no matter how sophisticated or how surprising Diana's research is considered by many to be merely the tip of the iceberg. But nonetheless, it is *** small step to better understand some of the creatures that rule the underwater world and seldom see.
