One Of Earths Most Inteligent Animals
Dolphins are one of earths most intelligent animals, they have been known to use ultrasonic sound for echolocation. Membership in their pods (see post "Interacting" and read about schools and pods) is not rigid; interchange is common. However, the cetaceans can establish strong bonds with each other, this leads to them staying with injured and ill individuals.

Be sure to check out the video I sent - here's some info about bubble blowing dolphins: When you spend your life in the water, I guess you tend to develop a good intuition for its subtleties. Dolphins have been observed to create bubble rings by exhaling air... More» carefully in the middle of the vortices caused by the motion of their fins through the water, among other techniques. Besides being nice to look at (and a neat demonstration of fluid mechanics), this phenomenon also might throw some light on dolphin cognition, since the skill to create the rings is a bit subtle and tends to be taught from one dolphin to the next via careful observation and practice. I'm also intrigued by the report that they seem to be using sonar to locate the vortex in the water, since that would be a fairly amazing bit of audio analysis. This video is dedicated to the best employee at Sea World. See more here: http://www.earthtrust.org/delringgallery.htm
