The carcasses of 120 river dolphins have been found floating in a tributary of the Amazon River over the last week in circumstances that experts suspect were caused by severe drought and heat.
Researchers from the Mamiraua Institute for Sustainable Development on Monday retrieve a dead dolphin from Lake Tefe, which flows into the Solimoes river, in Amazonas state, Brazil.
Amid the stench of decomposing dolphins, biologists and other experts in white personal protective clothing and masks continued on Monday to recover the dead mammals from a lake and conduct autopsies on the carcasses to determine the cause of death.The scientists do not know with certainty that drought and heat are to blame for the spike in dolphin mortality. They are working to rule out other causes, such as a bacterial infection that could have killed the dolphins.
Thousands of dead fish float in Piranha lake amid a drought in the state of Amazonas, in Manacapuru, Brazil, Wednesday, Sept. 27, 2023. Environmental activists have blamed the unusual conditions on climate change, which makes droughts and heat waves more likely and severe. Global warming's role in the current Amazon drought is unclear, with other factors such as El Niño at play.
