Alligator is disguised as a robot oversees the Mara River in Kenya. What is their job? The answer may be surprising, they are measuring the amount of hippode in the river and supervising the overall quality of the water.
At present, more than 4,000 hippos are treating the Mara River as a “toiletâ€, which researchers suspect is the culprit of fish deaths in the area. When the manure enters the water, it forms a large amount of bacteria and absorbs the oxygen required for the fish to breathe from the water. Now, the data collected by the robot is still being analyzed, and the reason why it is disguised as a crocodile is to prevent the robot from being attacked by a hippo that usually protects the territory.
