A Martian tweak from the Current Era, adapted to the atmospheric conditions that exist on Blue Mars. Additional nostrils at the top of the nose allow the tweak to breathe in and out in a cyclic fashion, absorbing extra oxygen from the 0.7 bar atmosphere.

An early Martian tweak of the Pre-Technocalypse Era, adapted to very low pressure environments. These tweaks did not remain on the planet once the atmosphere of Mars passed 100 millibars, since the thick atmosphere was uncomfortable for them. Most members of this clade have migrated to various locations in the Terragen Sphere since this time, particularly New Mars".
