One of a group of species with a white background and orange markings, Halgerda carlsoni is characterised by the orange-tipped rounded tubercles and the scattering of small orange specks all over the mantle between the tubercles. There is a band around the mantle edge devoid of small orange specks. The gills and rhinophores are speckled with black and in some animals the speckling can be dense leading to some sections of th gills being almost completely black. Other similar coloured species include Halgerda malesso, Halgerda sp. 1 and Halgerda aurantiomaculata.
