Co‐ordinated swimming and spatial co‐occurrence of tiger shark ( Galeocerdo cuvier ) at the Fernando de Noronha Archipelago, Brazil
Co-ordinated circular swimming by tiger sharks (Galeocerdo cuvier) was documented by divers in the Fernando de Noronha Archipelago, Brazil, on 1 October 2023 under non-provisioned conditions. At least six individuals maintained circular movement over 20 min. A second observation in October 2024 documented at least three sharks, although co-ordinated swimming could not be confirmed. Passive acoustic telemetry from 12 tagged tiger sharks revealed simultaneous detections of up to three individuals, indicating temporal co-occurrence near the site. These observations document an uncommon behavioral pattern and highlight the need for long-term studies.
