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.
