The natural history of Calyptraeaaurita (Reeve, 1859) from Southern Chile (Gastropoda, Calyptraeidae).

ABSTRACT: Hard bottom communities of the Reloncaví Estuary and adjacent areas, Region de los Lagos, Chile (42°S), were studied between 2008 and 2011. All hard substrates between the lower intertidal and 25 m depth were dominated by the calyptraeid gastropods, Crepipatelladilatata and C.fecunda. Epibenthic coverage of the hard bottoms markedly decreased further down with the exception of vertical cliffs. In a depth range between 26 to 48 m repeatedly dense patches of another calyptraeid species, Calyptraeaaurita (Reeve, 1859), were observed. Densities reached up to 1475 individuals m^-2 and covered up to 50 % of the rock surfaces. In shallower depths C.aurita was not present. However, despite its huge abundance, C.aurita has not been documented for more th
