The Sarapis blue creterler is a type of monkey like bleu creature having striking resemblance to the creterler of Horiat III leading some to believe that a group of one of them was placed on the other planet by some advanced alien race (probably the potaarde) leading to the evolution of the other one. Although this theory is not wildly believed among scientists. This creature has large ears and eyes which causes it to have vision and hearing over 6 times as good as that of humans. In the past these creatures where almost hunted to extinction until the frun started there current peacefull lifestyle.
