"This photo shows nicely the light-producing globe structures borne on lateral projections that characterise the genus Plocamopherus. Plocamopherus ceylonicus is identifiable by having the globes on only 2 pairs of lateral projections; 1 pair immediately in front of the gills and the other pair immediately behind the gills. This individual is slightly atypical in having pink globes; normally they are white."
