The drivers of resilience are key to understanding the responses of coral reefs under various threats. Corallivores, particularly obligate corallivores, may exacerbate the effects of stress on corals via predation. However, the extent and potential drivers of such negative impacts are unclear. Food availability, reef structure, and predator density, contribute to the variability in foraging behaviour. During periods of food scarcity, obligate corallivores may focus their predation efforts on a few coral colonies. Additionally, complex reef structures can enhance foraging success by reducing competition and predation risks. Such structures also provide shelter for piscivores, compromising corallivores foraging success and posing a threat to their survival. In this study, we quantified corallivorous bites in sheltered and exposed sites across the offshore GBR using the remote underwater videos (RUVs). We aimed to investigate how different compositions of coral prey, structural complexity, and the densities of corallivores and piscivores drive the variations in corallivorous bites. The cover of preferred coral prey and density of corallivores positively influenced the bite rate, while rugosity and density of piscivores had negative effects on it. By incorporating multiple covariates, we sought to gain a comprehensive understanding of this functionally specialized taxon.
