Popis: We evaluated the species composition, richness, and total abundance of the endolithic community in the skeleton of Orbicella faveolata under coral tissue and under turf algae using cores that were extracted at different distances (0.5, 2.5, and 7.0 cm) from both sides of the external coral tissue–turf algae competitive boundary. We found high endolith richness as never before reported for Orbicella species. Nineteen endolith taxa were found within the O. faveolata skeleton, seven below the coral tissue zone, and twelve exclusively below the turf algae zone. Significant differences existed in the community composition, species richness, and the total abundance of endoliths in the cores that were extracted from the turf algae zone compared with those of the coral tissue zone. The endolithic community composition and species richness changed abruptly across the coral–turf algae interface, forming a clear boundary between different endolithic communities just underneath the interface between the coral tissue and turf algae zones.
