Abstract: | Synopsis The relationships existing between the chaetodontid fishes and the surrounding coral communities were investigated in the
Gulf of Aqaba. Quantitative data were analysed by a correspondence and a cluster analysis. The results demonstrated a similarity
in the spatial distribution of both communities. Significant correlations were found between the density of chaetodontid fishes
and the diversity of the coral community as well as the substratum coverage by the coral colonies. The density of exclusive
coral browsers was also correlated to the abundance of branching colonies. Among the different genera of branching corals,
correlations were significant only for the genusAcropora. These results suggested the existence of strong links between coral and chaetodontid fish assemblages. |
