The longest recorded movement of an inshore common bottlenose dolphin (Tursiops truncatus)

Abstract Information on movements and connectivity among populations of animals is important for the delineation units to conserve, so that demographic parameters, such as abundance, fecundity mortality, can be placed in an appropriate population conservation context. Common bottlenose dolphins ( Tursiops truncatus ) are often considered relatively ‘resident’ demonstrating strong site fidelity specific areas. However, this perception may partly artefact distribution ‘habitat use’ cetacean researchers, rather than themselves, have been shown capable substantial movements, short periods time. Here, we report two long-distance a common dolphin within Mediterranean Sea, across Tyrrhenian, Ionian Adriatic Seas, subsequently back all three seas Ligurian making these longest recorded movement species Sea date some world. We also review published records worldwide. This study highlights utility photo-identification importance regional data sharing. argue comparisons always worthwhile results informative regardless presence or absence matches, especially with ongoing advances automated matching software.
