Overview
- A drone pilot recorded more than 100 sharks moving together near Bahía de San Antonio in Golfo San Matías, Río Negro.
- Experts identified the species as bacota shark (Carcharhinus brachyurus), with individuals estimated at 2.5–3 meters and roughly 80–100 kilograms.
- The footage was delivered to Grupo CONDROS at CIMAS for analysis, and exact coordinates are being withheld to deter illegal fishing and vessel disturbance.
- Researchers describe the sighting as highly unusual for the area and are testing hypotheses tied to migration or reproduction, with no cause yet confirmed.
- The species is listed as vulnerable and matures late at around 20 years, and scientists note there are no recorded bacota bites on people in Argentina.
