The organisms were randomly sampled from three zones: (1) the landward border of the top of an emergent reef (landward emergent reef -LER); (2) the seaward border of the same reef top (seaward emergent reef-SER); (3) the top of a submerged reef at 5 to 6 m depth (submerged reef-SR). Fifteen replicates of reef blocks (average 680 cm 3 sample size) were collected from each zone, twice a year, making a total number of 90 samples. A total of 1754 individuals comprising 40 species were found. LER samples contained 405 individuals represented by 17 species. Perinereis elenacasoae was the dominant species (58%). SER samples consisted of 1184 specimens, and Eunice wasinensis (73%) was the most abundant of the 30 recorded species. The SR samples contained 165 individuals represented by 22 ...

Coarse (gravel) sediments are relatively uncommon. • Previous work reported relatively high levels of siliciclastic-dominated sediments in the Abrolhos region, however high levels were not evident in most samples collected during the current study. The reason for this discrepancy is that bottom samples were collected close to reefs and therefore contained bioclastic material from reef organisms rather than sediment transported from shore. • Muddy sediments were mostly of biogenic origin, probably resulting from bioerosional activities of various boring organisms. • Abrolhos is characterized by a relict coral fauna that apparently has a relatively higher tolerance to muddy conditions than most modern coral faunas.
