Why do Sharks, Turtles Move in Circular Fashion? New Study Claims to Have Finally Solved the Mystery
News 18A particularly interesting feature about sharks is that these marine giants seem to swim in a circular motion all the time. The study was led by Tomoko Narazaki at the University of Tokyo and included tiger sharks, whale shark, green turtles, king penguins, Antarctic fur seals, and Cuvier’s beaked whale as samples. The study is the first of its kind to use emerging 3D technology to resolve the mystery behind this circular movement pattern. “We hypothesized that some circling may be related to magnetic-based navigation because circling movements seem to be well-suited to examination of the geomagnetic field,” she told the Inverse. While penguins, sharks used it to map available food, the turtles use it to map a way back home.
