did either of you by chance watch that special on animal planet...or discovery channel about the group of lifeguards that were swimming across a bay in New Zealand...apparently being stalked by a Great White... they didnt know it, they thought the dolphins were trying to attack them, they swirled around them corralling them into a tight circle, and wouldnt let them move for about 1hr, they slapped their tails on the water and stayed with them creating a barrier between the shark and the swimmers, the shark apparently grew tired of this and left, and as soon as it did...so did the dolphins!
This is a big deal because this means that the dolphins percieved a threat, and made a decision to put their own lives in jeopordy to save animals of another species! I really believe they have higher cognition, we just cant communicate with them (yet) so we have no way of knowing....
Another fascinating thing I learned during that program is that dolphins have signature calls for each individual (almost like a NAME!) when that signature call is played or vocalized by another dolphin, that dolphin comes in response!
I seriously think that evolution might have included humans evolving from sea creatures, and I bet dolphins were familiar with these ancestors , and know we could possibly be their descendants(i might be way off, but thats just my opinion!...but ive just always felt so at HOME in the ocean!)
....can you tell I love the ocean
