Onchidoris reticulata Wikipedia
This species was described from Playa de Artedo, Concha de Artedo, (43.56768°N 6.19105°W / 43.56768; -6.19105), Asturias on the North Atlantic Ocean coast of Spain.
Onchidoris reticulata has a translucent white body with brown-green surface pigment which is more intense towards the centre and clearer towards the edges. The area around the rhinophores is white or translucent with two longitudinal bands running backwards towards the gills. Thinner un-pigmented lines join the bases of the tubercles giving a reticulate pattern. Near the edge the pigmentation is reduced to a few widely spaced black scores.
