The northern hemisphere flow like features form at much lower surface temperatures and if they involve brines the temperatures are around -90 °C, too low in temperature to be habitable for Earth life, at least. Also, though most of the models for the northern hemisphere features involve water, they can also be explained with dry ice and cascading dust. <ref name="MartínezRenno2013DarkDuneSpots"/> |

The southern hemisphere Richardson crater flow-like features are the ones of most interest for brines at temperatures within the range of habitability for Earth life (life based on novel biochemistry based on perchlorates or hydrogen peroxide in the place of the chloride salts of Earth life might tolerate or prefer lower temperatures). |
