Seasonality and site fidelity of the zebra shark, Stegostoma fasciatum, in southeast Queensland, Australia

► We investigated site fidelity of zebra sharks to an aggregation site. ► Different mechanisms drive inter- and intraseasonal site fidelity patterns. ► Seasonal patterns are probably driven by endogenous cues such as photoperiod. ► Intraseasonal patterns are probably direct responses to unfavourable conditions. ► Abiotic variables may predict changes in movement under different future scenarios.
