Why do sea turtles need to get rid of salt in their bodies while they're nesting?

The Green Sea Turtle has many special adaptions for life in the oceans. One of them is the ability to rid their body of the excess salt that builds up from living in seawater, and their diet. The Sea Turtle has a "salt excretory gland" behind, or in the corner of each eye, and this helps regulate the amount of salt in their body, thus maintaining a healthy water balance. It makes the turtle appear to be crying when they shed big tears, but they are really just adjusting the amount of salt in their systems. For more details, please see the sites listed below.
