How does the human being appear in the eyes of dolphins?

Dolphins emit acoustic waves to recognize surrounding objects "Echolocation(Echo location) "is known to have the ability to", but research has revealed how dolphins are looking at people in the sea.

The following image shows how dolphins are looking at humans, left side is underwater picture, right side is high resolution version. You can see that the human silhouette is clearly shown. This research is an NPO organization that is investigating dolphin communicationSpeakDolphin.com"Founder Jack Kassewitz said," We saw the results of the research and we all lost words. "


The research was conducted at the Dolphin Research Center in Puerto Aventuras, Mexico. Kassewitz, with team member Jim McDonough, dives in front of the female dolphin Amaya swimming in the research pool in the center. When breathing in the water, bubbles appear in the image, so the two people exhaled as much as possible and dive in the water, and wrapped the weight belt so that the body did not float. When Amaya recognizes the two who dive in the water, he sounded a sound wave and the staff on the ground recorded the sound wave with a high-performance audio device.

Data recorded in the water was sent to the research facility of CymaScope in the UK, and acoustical physicist John Stuart Reid output data. CymaScope said that it uses holographic-like technology to convert dolphin's view into an image. From the outputted images, it was found that dolphins recognize the human figure in detail by using the "echo location" ability to measure the presence of objects using sound waves. The distance between Amaya and Kassewitz was several meters apart, Amaya recognized the whole human body, but the members of SpeakDolphin.com initially saw "the dolphins clearly see the human face It is supposed that dolphins are actually recognizing only the human silhouette.

In addition, the research team speculates that dolphins are using languages ​​that use "sound and video", and I believe that dolphins share the videos they saw. "If this hypothesis is true, Kassewitz will be interested in future research on animals' communication skills," he says.

In order to capture the dolphin's vision more precisely, the technology of human beings is still not catching up. According to Kassewitz, "Dolphins have evolved echolocation capability over 50 million years, but marine biologists are only doing research for about 50 years, I only have about 5 years Since I have not studied, I need to continue research in the future.
