A Martian tweak from the First Golden Age of Mars, during the Federation era. The low gravity on this world allows this clade to attain an average height of 2.75 metres. These tweaks are tolerant of high levels of greenhouse gases, such as carbon dioxide and halocarbons.

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.

A pantropic tweak, adapted to very low pressure environments, living on some Arean planets similar to pre-terraformation Mars. These tweaks generally inhabit worlds with an atmosphere of less than 100 millibars, since a thick atmosphere is uncomfortable for them. Many members of this clade can be found on New Mars.
