Comparative Space Use of Sympatric Sharks at a Remote Island in the South Pacific Ocean.

ABSTRACT: Seamounts and offshore islands support unique assemblages of sharks. The aim of this study was to contribute to the limited knowledge of how co-existing shark species partition spatial resources at these remote bathymetric features, particularly those influenced by a mix of temperate and tropical oceanographic conditions, as well as human activities. The space use of 34 dusky (Carcharhinus obscurus), 32 Galapagos (C. galapagensis), 47 tiger (Galeocerdo cuvier), and 20 sandbar (C. plumbeus) sharks was monitored with acoustic telemetry between 2021 and 2024 in coastal waters around Norfolk Island, Australia, a remote island in the southwestern Pacific Ocean. Seasonal patterns of residency and fine-scale site fidelity were compared across species during this multi-
