Are turtles affected by city lights?



  1. 0 Votes

    Turtle hatchlings are confused by the artificial light at beaches.  They instinctually move towards the light, because before there was artificial light the dunes and vegetation looked dark, while the ocean (their destination) reflected the moonlight. When artificial lights are present, the hatchlings may get confused or walk in the wrong direction, causing them to die from exhaustion or being run over by cars.

    It also appears that female turtles prefer to nest on the less-developed, poorly-lit beaches.
