Abstract/Description: Parrotfish play an important role on coral reefs through their direct consumption of algae and are known to occasionally prey on live corals, leaving visible scars. In this study, we examined how parrotfish scarring was distributed around the island of Moorea, French Polynesia and how it varied between habitats. To understand the potential drivers of this scarring, we investigated the relationship between grazing intensity and parrotfish biomass, coral and algal cover. We ranked grazing intensity on a scale of zero to three according to the degree of scarring on the coral compared to its total surface area. We found that the distribution of grazing intensity around the island and between habitats was significantly different. We also found that scraper biomass (positive relationship), coral cover (negative relationship), and rubble cover (positive relationship) significantly contributed to grazing intensity. As coral reefs continue to be impacted by anthropogenic changes, understanding the drivers and consequences of corallivory will become increasingly important.
