At the end of winter and beginning of spring time in Brazil, more than 100 dolphins have been found dead on Brazilian Amazon river shores amid a severe drought in the area.
Most of the dolphins have been found in Lake Tefé, reported CNN, which is a branch of the Amazon River located in northwestern Brazil.
In Lake Tefé there are about 1,400 river dolphins, according to the Mamirauá Institute for Sustainable Development. With an about 120 deaths, almost 10% of the population is gone.
Experts suspect warmer-than-usual water temperatures are to blame for the deaths, as the area is experiencing severe drought. The heat wave in the area has heightened water temperatures, which reached 102 degrees Fahrenheit in recent days.
Brazilian river dolphin species feed on fish, which local media has reported are also dying from the warmer water temperatures, making the situation even worse.
