Stony corals of St. Eustatius

Previous surveys of the coral fauna of St. Eustatius were usually of short duration and part of a larger research that included all of the windward Netherlands Antilles (SSS = Saba, Saba Bank, St. Eustatius, and St. Martin). This may have caused an underestimation of its species richness. In an expedition to the Saba Bank in 1972, one sampling station (maximum depth 15 m) was added at the west coast of St. Eustatius, which resulted in a record 16 stony corals species from this island (Van der Land 1977). Bak (1975) visited all SSS islands from where he reported a total of 35 scleractinian species (< 35 m depth). Sybesma et al. (1993) listed 16 reef coral species. Klomp and Kooistra (2003) found 23 scleractinian species (partly specified), which they recorded from the windward islands, including 10 dive sites off St. Eustatius. Jongman et al. (2010) listed a total of 41 scleractinians but it is unclear how this information was obtained. The most recent inventory included 24 scleractinian species for St. Eustatius (Debrot et al. 2014). Since the coral faunas of Saba, Saba Bank, St. Eustatius, and St. Martin do not show a clear variation (Klomp and Kooistra 2003) the present results are compared with the previously published records (except for those in Jongman et al. 2010). In this way it may become clear if certain species have disappeared or became introduced (Hoeksema et al. 2011).
