stingrays tend to congregate in shallow waters, and are therefore commonly found where the tide meets the beach - for this reason it is often advisable to avoid swimming when the tide is low in strands that can be found in rio de janeiro state, secluded and farther from constant human activity.

the stingray is very well adapted to its surroundings, commonly camouflaged to blend imperceptibly with the golden ocean floor - they lie dormant, or inactive, for large periods of time, buried in the sand, swayed by the moving tide.

they have a predilection for muddy waters, which compounds the existing difficulties in spotting them - he eyes of the stingray are on its side and scientists believe they play a very limited role in the sea-creatures activities, as it instead uses sensors to perceive the electrical charges of potential prey.
