    Abstract

    Background: The presence of parrotfish species in tropical reef habitat has a crucial importance for benthic species distribution, among them coral species that are predated by corallivory. Due to the important role this group plays on coral reefs, shedding light on parrotfish distribution patterns contributes to the understanding of barrier reef processes, thus supporting conservation efforts. Methodology and Principal Findings: The study was conducted in the Belizean barrier reef, part of the largest Mesoamerican Barrier Reef System, were three different habitats were sampled, the reef crest, the shallow fore-reef and the deep fore-reef. Parrotfish species density and biomass were estimated from fish transects and the incidence of coral predation was calculated from number of parrotfish coral bites on coral colonies across transects. Conclusion: This study investigated the changes in parrotfish predation intensity on corals across reef habitats and the relation between predation intensity and presence of parrotfishes, calculated as density and biomass. The results offer insights on how the intensity of coral predation by parrotfish species vary among habitats within a single reef, and suggests that there is no correlation between parrotfish abundances across reef habitats.
