Why do Sharks, Turtles Move in Circular Fashion? New Study Claims to Have Finally Solved the Mystery

News 18  

A 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.

Species of turtle, shark, penguin, seal and whale swim in circles - but scientists don't know why

Daily Mail  

Species of turtle, shark, penguin, seal and whale swim in circles, new research shows – but scientists aren't sure why. 'We've found that a wide variety of marine megafauna showed similar circling behaviour, in which animals circled consecutively at a relatively constant speed more than twice,' said study author Tomoko Narazaki at the University of Tokyo. Narazaki's team first discovered …
