Reports regarding marine life in Brazil indicate both individual mortality incidents and broader signs of species recovery. In late August, an adult male humpback whale was found dead on a beach in Itanhaém, São Paulo. While the Instituto Biopesca suggested the whale may have interacted with fishing activities, the advanced state of decomposition prevented a precise determination of the cause of death.

By mid-September, observations suggested a significant increase in whale sightings along the coast. In Rio de Janeiro, humpback whales were observed in Guanabara Bay near Copacabana, Ipanema, and Leblon, including the sighting of three calves. Additionally, southern right whales, typically found in Southern Brazil, were sighted in the Southeast, with rare photographic evidence of mating behavior recorded near Imbituba, Santa Catarina.
