 +Safìr are hexachromats; they can see ultraviolet, and their six types of cone cells have evolved such that their maximal absorption peaks are roughly equally spaced, unlike in humans. Four of those cone cells are devoted to the human-visible spectrum, and the longest two to different wavelengths of ultraviolet.
  
 The safìr vocal apparatus is a syrinx, like that found in songbirds, rather than a larynx, as found in Terran mammals. The safìr vocal apparatus is a syrinx, like that found in songbirds, rather than a larynx, as found in Terran mammals.
