Description
Diversidoris is a small genus of chromodorid nudibranchs (family Chromodorididae) with four species listed on Wikipedia, supported as a clade by molecular analysis. The species are known from the tropical western Pacific and southern Australia; they are small (up to about 1.5-5 cm) and feed on yellow sponges such as Darwinella and Aplysilla sulfurea, whose colour they mimic.
Identification
A vivid yellow body, including the rhinophores and gills, with a thin red line or orange spots along the mantle margin (for example in D. flava and D. sulphurea). The mantle narrows centrally, giving a pinched look with semi-permanent folds. Because the colour mimics the sponge, separating the species is difficult.
