By adjusting the volume of sonar clicks, then processing the incoming echoes, dolphins solved a problem that still stymies man-made sonar: how to peer through frothy water. This discovery is recorded by Sunstroke author David Kagan in Doomwatch Legacy.

I had found this out yesterday and was astonished, but not surprised. They are much smarter than humans ~ I know that!

And? Why are people so surprised that animals are smart? We do not own the patent on intelligence although we act like it. I would say that animals are smarter than us as they do not need all the accoutrements to live. Well, we don't need a lot of them either but somehow it is called progress when they are invented.

A creature who lives in a world of sound will learn to make the best use of it to see the environment the animal lives in. Dolphins have learned an expert system to handle natural sonar imaging much as we learn an expert system to process vision, or to encode and decode speech.

It is simply amazing what dolphins can do and teach us! They are true masters of the marine world in their capacities to use echolocation superior to our sonar and locate prey in murky or frothy waters and scientists are learning from them how they might be able to do this- that nonlinear mathematics maybe behind these mammal's ability to see through bubbles and dolphins can perform all these complex mathematics naturally in their brains without help from computers!

noted...i love the dolphins and only wish they could all be set free from these amusement parks that use them as "trick displays" again for the love of money....so sad that they are taken out of their natural environment and put on display.....i

Animals have brains but no understanding of knowledge, Humans have knowledge but no brains, if they (Humans) did have brains they would not do all the horrible things that they do!!!

When I lived in La Jolla, attending UCSD, my then husband (still one of my best friends), who was a grad student, worked at Scripps. They were testing a device that would save tiny crabs from the harming and deaths that they were forced to endure with certain man made activities on the sea floor. I am happy that Scripps is ecologically forward, and recognizes / respects life forms as the intelligent parts of the Universe that they are.
