摘要: The present study investigated the distribution and abundance of epibenthic molluscs their feeding habits associated to substrate features (coverage rugosity) in a sandstone reef system Northeast Brazil. Rugosity, low coral cover high coverage zoanthids fleshy alga were variables that influenced richness few molluscan species habitat. most abundant generalist carnivores, probably lesser offer variability resources this type system, when compared reefs. results found could reflect normal characteristic community reefs, with cover, or indicate degradation state habitat if it is once significantly has been recognized as negative indicator ecosystems health.
