Iguanas have a very specific way of getting rid of excess salt from the body. They take salt together with marine algae that they feed on. Because the reptiles cannot sweat and get rid of slat excess they must do it in other way. I you watch the movie until the end you will see Iguana on a certain “road” sign and then you know how they get rid of salt J

As always, I encourage you to share the film

All the best
