Hundreds of freshwater dolphin corpses have emerged from the Amazon River, suspected to be related to extreme drought and high temperatures

Last week, about 120 floating bodies of freshwater dolphins appeared in a tributary of the Amazon River in Brazil. Experts suspect that the cause of freshwater dolphin death may be related to extreme drought and high temperatures

Last week, about 120 floating bodies of freshwater dolphins appeared in a tributary of the Amazon River in Brazil. Experts suspect that the cause of freshwater dolphin death may be related to extreme drought and high temperatures.

Researchers believe that during severe drought periods, the water level of the Amazon River in Brazil was too low, leading to an increase in water temperature in the river section, making freshwater dolphins unbearable and subsequently dying. Recently, thousands of fish on the Amazon River have died due to lack of oxygen in the water.

At present, scientists cannot fully determine whether the soaring mortality rate of freshwater dolphins is related to extreme drought and high temperatures. Therefore, researchers are working to rule out other reasons, such as the presence of a virus in a lake before the tributary flows into the Amazon River that can cause bacterial infections and death in freshwater dolphins.

It is reported that the temperature of this lake once soared to 39 degrees Celsius last Thursday (September 28th), more than 10 degrees Celsius higher than the average temperature of the same season in the past. Subsequently, at least 70 bodies of freshwater pufferfish surfaced.

Mamontel pointed out that the proportion of deaths of Aragona pufferfish in Lake Teffe may account for 10% of the total number of dolphins living in Lake Teffe.

The Amazon River is home to a large number of pink Araguana pufferfish, which are particularly vulnerable to survival threats due to their slow reproductive cycle. The Aragona pufferfish is a unique freshwater species that only exists in the rivers of South America and is also one of the few remaining freshwater pufferfish species in the world.
