Table 2.

Interaction matrix between amphiprionine anemonefish (columns) and their sea anemone hosts (rows). Filled squares indicate a known interaction. The grey line is the isocline for this dataset, above which all interactions would lie in a fully nested matrix. The extent of the grey shading around the species names indicates whether the species is local, regional or widespread in distribution. An X in a cell indicates that the fish and the anemone do not overlap in their distributional ranges (n=43 out of 137 zero-interaction cells). Note that M. doreensis is a host of A. chrysopterus and not A. chrysogaster as incorrectly recorded in Fautin & Allen (1997).
