Scientists Create First Image Ever of How Dolphins See Humans
For the first time ever, scientists have reproduced an image of what a dolphin would see when it encounters a male diver.
This image projected what the dolphin is seeing, when a submerged man was detected by the dolphin via echolocation, with somewhat accurate details. Scientists now believe that dolphins even share these images with each other as a previously unknown marine mammal form of communication.
According to lead researcher Jack Kassewitz from SpeakDolphin.com, this recent breakthrough left us speechless and and now it can be safely assumed that dolphins use a "sono-pictorial" type of language where they use pictures to share with each other, providing exciting clues about inter species communications.
This new study is conducted in the Dolphin Discovery Center located in Mexico along with colleague Jim McDonough who submerged himself in the research pool with the dolphin test subject "Amaya". McDonough avoided using a breathing apparatus that may produce bubbles to avoid disrupting the recreation of the image later.
When Amaya directly beamed her echolocation on McDonough, the team used their high specification audio equipment in order to record this signal. Researchers then sent this recording to CymaScope Laboratory in the U.K., where acoustic physics researcher John Stuart Reid used this signal to make an imprint on a water membrane where it was later enhanced digitally as the final image.
Reid explains how CymaScope captured the dolphin's conceived images and then revealing the holographic qualities of sound in relation to the water. The final image revealed a fuzzy silhouette of an almost full man however, with no distinct facial features.
Apparently, Amaya the dolphin has been echolocating McDonough from seven feet away before she hovered closer, where researchers captured her more distant signals.
Researchers conclude that using CymaScope to capture what the dolphin saw, this research shows how dolphins can at least see a full silhouette via their echolocation sound senses. However, scientists still believe that these dolphin echolocation signals can still reveal clearer signals and more detailed mental images since human technology still cannot match with the marine mammals' signals.
