Freshwater turtles navigate using the sun
(PHYSorg.com Biology)

Blanding`s turtle hatchlings need only the sun as their compass to guide them on their way to the nearest wetland-and a place of safety. This is according to John Dean Krenz of Minnesota State University in the US, lead author of a study in Springer`s journal Behavioral Ecology and Sociobiology. The study focused on how this freshwater turtle, native to the US and Canada, is purposefully able to travel in a relatively straight line once it has hatched.
