The flat turtles actively swim as babies against ocean currents to stay within the Great Barrier Reef in the northeast of Australia, according to a study released today.
The research Wildermann Natalie, James Cook University, found that it was impossible for the hatchlings of these turtles (flatback sea turtle) remain within the limits of the Great Barrera only by the fact of being carried by ocean currents.
The work was based on computer models of ocean currents to show that the flat turtle hatchlings should actively swim against them to stay within these reefs.
“It was believed that the baby sea turtles drifting passively on the sea currents and these currents carried them favorable habitats for their development. But recent studies, including ours, show that actually actively dispersed, “he said Wildermann.
” (Turtles) swim and do it in a certain direction to achieve or avoid currents ” He added the researcher said in a statement from the university.
It remains unclear how the young of the flat turtles learn how and where to swim, although it is presumed that they are guided by magnetic sounds, like other species . , or surf the help of basic chemical clues
