A school of more than 100 sharks was found by a group of divers and researchers, in the Alcatrazes archipelago, on the north coast of São Paulo, last Monday (17).
According to the Chico Mendes Institute for Biodiversity Conservation (ICMBio), which manages the archipelago, the group of animals was made up of hammerhead sharks and possibly another species.
The Alcatrazes Archipelago, which is about 35 kilometers from São Sebastião, has always been inhabited by sharks, according to ICMBio, however, due to the creation of a Federal Integral Protection Conservation Unit there has been an increase in the appearance of these species.
“The presence of these animals is an important indicator of conservation and marine balance, being positive and desirable, including from a tourism point of view”, said Thais Farias Rodrigues, head of ICMBio Alcatrazes.
The Institute that manages the group of islands also explained that the increase in fish biomass in the archipelago, following the reduction in illegal fishing, also led to an increase in the presence of larger schools of sharks.
Among the most recorded species at the site are the hammerhead shark, silky shark, mangona shark and the chicken dogfish. Contrary to the thinking of many, these species do not have aggressive behavior, and diving and other activities can occur calmly, according to the Chico Mendes Institute.
