The turquoise-colored adults had the ability to speak with their mouths, but they could also communicate by using ultrasonic waves created within their large crania. Their enlarged heads earned them the nickname "lumpheads" from the Imperial forces that occupied Monor II during the Galactic Civil War. The Sunesi have long, thin limbs, and four thin fingers on each hand. The blood of a Sunesi was bright pink in color. The fact that all living adults had survived the metamorphosis evolved into a species-wide belief in reincarnation.
