Fig. 4. Representative orientations of three juvenile loggerhead turtles tethered
in the experimental arena. Each turtle is denoted by a different symbol. Time
is indicated along the horizontal axis and the angle of orientation is
indicated along the vertical axis. Each dotted line represents the mean
heading of the turtle over its 10 min trial. Once a turtle established a
course, it typically maintained relatively consistent headings for the
duration of the trial.
