More than 100 dolphins have died in the Brazilian Amazon rainforest in the past week as the region grapples with a severe drought, and many more could die soon if water temperatures remain high, experts say. The Mamiraua Institute, a research group of Brazil’s Ministry of Science, Technology and Innovation, said two more dead dolphins were found Monday in the region around Tefe Lake, which is key for mammals and fish in the area. Video provided by the institute showed vultures picking at the dolphin carcasses beached on the lakeside.
Researchers are still weighing options but the best candidate for the deaths is warmer water and drought. Are there dolphins in the Amazon? How many Amazon River dolphins are left?
MANAUS (Reuters) -The carcasses of 120 river dolphins have been found floating on a tributary of the Amazon River since last week in circumstances that experts suspect were caused by severe drought and heat. Low river levels during a severe drought have heated water in stretches to temperatures that are intolerable for the dolphins, researchers believe. Thousands of fish have died recently on Amazon rivers due to a lack of oxygen in the water.
