The Andorian retina is composed entirely of tone-sensitive rods, and
is incapable of discriminating between differing wavelengths of light.
Therefore, the addition of color to the Andorian's vision is accomplished
by the dual antennae which, in addition to being auditory receptors, are
made up of a complex network of wavelength-sensitive cones. Owing to the
highly directional nature of the antennae, the corona of vision is
perceived by the subject in tones of grey. Because of this correlation of
four independent light-receptive organs, Andorian vision can correctly be
termed "quadriscopic", resulting in relatively (humanoid) superior depth
perception. Andorian auditory capabilities are highly developed, and
Andorians are capable of distinguishing from among a wider variety of
audio frequencies than is normal for humanoids. Because of the
monodirectional antennae, Andorians usually tend to listen with their
heads tilted slightly downwards. Note the limited exoskeleton.
Yon FASA game Supplement sez:
ANdorian physiology has influenced every aspect of Andorian life, from the
laws and mores of the Andorian people to their history and their relations
with other races of the Federation. With their robin's egg blue skin color
and pure white hair, the physical appearance of Andorians is remarkable in
the Federation. This color pattern is due to the high concentration of
cobalt in the hemoglobin of Andorian red corpuscles.
In general the humanoids of Andor are believed to have originated among
the ice and glaciers of the polar continent in the southern hemisphere of
the planet. As Andorians are endothermic to a degree, they have
difficulty keeping their temperatures down to the usual 57 degrees C when
in temperatures over 44 degrees C. At higher temperatures, they lose their
highly-touted logical minds, and tend to become cunningly violent.
Standard gravity for Andor is approximately 1.17 times the Terran G.
