The image is a photograph of a sign that reads "Freshwater Sting Rays". The sign is located on a wooden stand and is located in front of a tree trunk. The sign has a blue background with white text. On the right side of the sign, there is an illustration of a stingray with its mouth open, as if it is about to take a bite out of the water. Below the illustration, there are three smaller illustrations of different types of stingrays. 

The first illustration on the left shows a flat, flexible ray, which is a type of stingray that is native to South America and Asia and Africa. The second illustration shows a tropical river with a boat on the water and a sunset in the background. The third illustration shows two stingrays, one with white spots and the other with black spots.

Overall, the sign provides information about the different types and habitats of freshwater stingrays in South America.
