The specimens were found in the Tefé River, one of the tributaries of the Amazon, where the Mamirauá Institute, linked to the Ministry of Science and Technology of the South American giant, carries out sustainable development programs in the city of Tefé, in the Brazilian Amazon.

According to the research center, most of the animals found belong to the species commonly known as the pink dolphin (Inia geoffrensis) and also some specimens of tucuxi (Sotalia fluviatilis), river cetaceans in serious danger of extinction. In Lake Tefé alone, 110 bodies have appeared since last September 23.



According to Miriam Marmontel, leader of aquatic mammal researchers at the Institute, "It is still early to know the cause of this extreme mortality event, but according to our specialists it is certainly associated with the current period of drought and the high temperatures of the lake," he claimed.

The specialist highlighted that the temperature recorded in Lake Tefé, at depths of up to three meters, has reached up to 40 degrees in recent days, when it is generally 32 degrees Celsius, which increases the acidity of the waters.



Likewise, it emerged that the severe drought that has pushed the Amazon to minimum levels.

Said climate problem caused the death of tons of fish in Lago do Piranha, a lagoon near Manaus, capital of the state of Amazonas and the main city with the largest tropical forest reserve in the world.

The Institute stated that it is concentrating its efforts on discovering the causes of the mortality, but also on saving the animals that are still in the lake, since this fact further increased the risk of extinction of these species that in the 2010s amounted to 900 pink dolphins and 500 tucuxis in the Tefé Lake basin.
