The sea has been washing up bodies since June: dozens of dead baby whales in Argentina

The sea has been washing up bodies since June

In recent weeks, dozens of baby whales have been found dead on the coast of southern Argentina, in Chubut province. The first dead animals began to wash up in the sea in June. Experts point out that the number of deaths among young animals is much higher than in previous years.

A deadly infection attacks the youngest whales

Veterinarians suspect a possible outbreak of erysipelas infection, a serious disease caused by bacteria naturally found on the skin of whales. This disease may be particularly dangerous for young individuals whose immune systems are not yet fully developed.

Scientists study human influence

The cause seems to be natural, but we cannot completely exclude the influence of human activity, emphasizes Mariano Coscarella, a researcher from the Marine Mammal Laboratory of the Conicet national research council.

Chubut provincial authorities said they are working closely with the scientific community to solve the mystery of the dying whales. Experts continue to search for other potential factors. Particular attention is paid to the analysis of the environment, changes in the ecosystem and the possible impact of human activity.

A record year and a sudden population decline

Puerto Madryn and the Valdés Peninsula are key breeding grounds for southern right whales, also known as right whales. These impressive mammals reach up to 17 meters in length and weigh on average 40 tons. They can live up to 60 years.

In 2025, a record number of 2,110 whales were observed in this area, including as many as 800 young ones. However, this year these numbers have decreased - 1,375 individuals were counted, including almost 400 calves.

Despite the disturbing number of deaths, experts reassure us that the current situation does not pose a threat to the survival of the population.
