@firefly,
well considering that earthlings have two and martians have three i would have to go with 1.
and since earthlings have green blue and brown eyes which are the colors of the earth. and martians have red eyes(cuz it supports my opinion)... venutian eyes would have to be teal(because i like teal)
and of course if it was a mercurian ocelot that migrated to venus but the ocelots mom was from jupiter and his dad was from saturn he would then have 5 and 1/2 eyes.
