This "what the dolphin saw" image of the submerged man reveals that dolphin echolocation results in fairly detailed images. What's more, it's now thought that dolphins may share such images with each other as part of a previously unknown marine mammal language.
Research team leader Jack Kassewitz of SpeakDolphin.com said in a press release that "our recent success has left us all speechless. We now think it is safe to speculate that dolphins may employ a 'sono-pictorial' form of language, a language of pictures that they share with each other. If that proves to be true an exciting future lies ahead for inter species communications."
For the research, which took place at the Dolphin Discovery Center in Puerto Aventuras, Mexico, Kassewitz had colleague Jim McDonough submerge himself in front of the female dolphin "Amaya" in a research pool at the center. To avoid bubbles from a breathing apparatus (which might have hurt the later recreation of the image), McDonough wore a weight belt and exhaled most of the air in his lungs to overcome his natural buoyancy before positioning himself against a shelf in the pool.
Comment: As the number of volcanoes erupting right now is greater than the 20th century's YEARLY average, a comparable escalation in activity of their underwater counterparts seems logical. There has been a dramatic increase recently in seismic and volcanic activity, particularly around the Pacific Ring of Fire region.
It is estimated there are up to one million submarine volcanoes on our planet. Effects from this volcanic activity, combined with increased methane outgassing, radiation from the Fukushima disaster are probably also causing the ongoing devastation of marine life, mass fish die offs and strange migratory behaviour of rare fish we are currently witnessing.
