Based on a recent study conducted by researchers at the Dolphin Discovery Center in Puerto Aventuras, Mexico, dolphins have Facebook-like vision. Scientists used special programs to translate and interpret dolphins’ echolocation signals into images.
Dolphins’ language has made the subject of many previous studies, but it was only recently that researchers at the Dolphin Discovery Center in Puerto Aventuras in Mexico have decided to turn their attention towards dolphins’ vision. For a better understanding of mammals’ visual abilities, marine biologist Jim McDonough submerged himself in front of dolphin Amaya.
The diver did not wear a normal breathing apparatus, but preferred to naturally exhale the air in his lungs to prevent image distortion. Jack Kassewitz, the lead author of the current study, used special computer programs to record the echolocation signals emitted by Amaya upon noticing the diver in the water.
The recorded sounds were then sent to a special lab in UK, where CymaScope images have been recreated, based on signals. Scientists used both an original and a computer-enhanced images to compare and to understand dolphins’ vision.Researchers were surprised with the finding of their latest study. The original CymaScope image is somewhat fuzzy, but it is clear dolphins can perceive human shapes. In addition, researchers have reasons to believe dolphins are capable of surface vision because both images showed the diver’s belt.
Jack Kassewitz was even more impressed by the fact that dolphins have Facebook-live vision. To be more specific, dolphins use echolocation signals to share the images they capture with other mammals. It is unclear why they do this, but scientists plan to find out more about this phenomenon in their future studies.
The team of researchers admits there may be weaknesses in their study. The computer programs that scientists are currently using may not be sufficiently advanced to reproduce the exact images that dolphins perceive. Nevertheless, knowing that dolphins share images with each other, is a good starting point.
Researchers think such flaws and weaknesses are natural as dolphins’ language and vision senses have evolved in fifty million years. Scientists, on the other hand, have acquired the necessary scientific tools five decades ago.
