The Sokuja are aliens, and thus any attempt to apply a Terran classiﬁcation systems to them is inherently difficult and misguided. That being said, from the Terran point of view, the Sokuja display a mixture of mammalian and reptilian features. From the waist up, they appear human with light body hair and long head hair. The males do not grow beards. They display the same range of skin tones as humans, with a predominance towards the darker shades. The Sokuja bare live young (usually single births) and the females have breast for nursing them, but the oily-amber liquid produced for the suckling infants bare slittle resemblance to milk. From the waist down, the Sokuja have a seven foot long sinuous snake body. The genitals are located slightly below the navel,and are covered by ﬂaps of scaled skin most of the time. They are unnoticeable except during intense arousal. Total length is roughly ten feet for both males and females, with the females being notably lither. They weigh twice as much as an equivalent human, but thanks to a lower metabolism eat roughly the same amount. This lower metabolism also gives them a natural life expectancy of 120 years.
Sokuja do not traditionally wear clothing or armor of any kind. Space suits are considered an uncomfortable necessity.They are however very found of jewelry.Because they don’t have pockets to carry items, they design their technology to be wearable(cell phone earrings, computer bracelets, tool belts,visual display sunglasses, etc.) The Sokuja are aware of human sensibilities, so the females will cover their breasts when dealing with humans, most of the time.
The current theory to explain their morphology is that they evolved from freshwater predators of ape level intelligence. These proto-sokuja appear rather similar to the earth manatee or dolphin. When continental drift stranded a population of the proto-sokuja in an dead sea, they evolved an upright posture to keep their eyes out of the brackish water, and scales to protect their lower bodies. The need for fresh water caused them to start eating fruit, so their ﬂippers evolved hands for climbing trees. Long hair on their heads evolved for the young to cling to while swimming.All the while, the harsh living conditions encouraged intelligence. Finally the dead sea turned into a salt ﬂat and forced them onto dry land.
