Once one dolphin noticed, every single dolphin came to check it out at some point. So yes, I certainly think they talked to eachother. Called the others over to see it.
The trainers were amazed as the rest of us. They told me they have RC cars and trucks they play with in the viewing area and the dolphins chase them across the glass, but that is a game for them. Those are toys. The trainers were mostly speechless. With "oh my god"s now and then, so I would say the dolphins' reactions was brand new to them. I didn't have time to talk to them after. I really wish I asked them for an on camera interview or something, lol.
Also, this was the first time Pleo herself seemed so interested in something. Dogs, cats, even people, she eventually walks away to explore something else. But this time, she stayed put and watched them and often made vocalizations. I did not use the original camera audio because it was packed with people and you can barely make out much. And you can't hear Pleo at all. But the Pleos make lots of vocalizations. I believe Ugobe, the company who makes them, said they have as many as 400. I could be wrong on that, but I could have sworn it was 400.
And yes, Ugobe liked the video so much, they posted it on their front page and on their Twitter blog too
