Humpback whales return to dominate Brazil's coastline after decades on the brink of extinction

oglobo29 August 2026 at 04:01

In the largest humpback whale reproduction sanctuary in the South Atlantic, on the Brazilian coast, the presence of these animals has once again become a common sight. In Abrolhos, in extreme southern Bahia, males compete for females while scientists closely monitor a population that went from nearly extinct in the South Atlantic four decades ago to approximately 35,000 individuals today.

The Abrolhos archipelago, located about 70 kilometers off the coast, welcomes the whales between June and November. In the warm waters of the region, females give birth and nurse their calves, while males seek to mate.

The species' recovery was the result of the prohibition of hunting, the protection of reproduction areas, and decades of research to understand the behavior and movements of the species, according to the National Institute of Amazonian Research.

Do you eat while working at the computer? Experts warn that the keyboard can be a "bacteria cafeteria"

Experts warn that eating while working at the computer can turn the keyboard into a true bacteria reservoir. When people eat in front of the computer and continue typing without washing or sanitizing their hands, crumbs, food residue, and moisture accumulate on the keyboard, creating ideal conditions for microorganism proliferation. The habit, although seemingly harmless, can pose health risks, as keyboards accumulate dirt over time and can transmit diseases. Experts recommend regular hand and keyboard hygiene to avoid contamination.
