A great one-horned rhinoceros cools off in its pond at Berlin’s Zoologischer Garten Zoo on June 5, as temperatures climbed past the 30 degree Celsius (86 Farenheit) mark. These endangered animals— they are only about 2,500 of them left in the world—are hunted illegally for their horns, which are believed (wrongly) to have medicinal powers. A mature great one-horned rhino can weigh as much as 6,000 pounds.
