Evolution
Cielioids evolved from a tumbleweed-like plant species. Here is a brief evolutionary history of the Cielioid race.
Nutrition
Their skin is typically slightly photosynthetic, and young Cielioids have vestigial root systems. Despite this, Cielioids derive most of their nutrition from eating food. Cielioids are omnivorous.
A Cielioid needs to breathe an atmosphere containing both Oxygen and Carbon-dioxide, because Cielioid metabolism has both plant-like and animal-like components. These components do exchange by-products, which makes their metabolisms efficient and highly adaptable. In a low-oxygen environment, a Cielioid will seek out light sources to stimulate photosynthesis, and in an environment with little carbon-dioxide, a Cielioid will tend to eat and exercise more to make up the difference.
Life-Cycle
After a Cielioid seed-pod is planted in the podding-ground, it is tended by caretakers as it matures over a period of months. When the pod opens, the juvenile Cielioid is fully formed, but rooted to the ground, where it remains for several months before learning to walk. The young Cielioid is watched over by the caretakers at the podding ground until it is old enough to start formal schooling, a couple years later. School continues for a period of time, and in subjects both determined by subspecies. Cielioids typically reach physical maturity in about fifteen years. After finishing school, the Cielioid joins the workforce as an adult. Cielioids typically live about one hundred fifty years, depending on subspecies.
Going to root
“Going to root” is a rare phenomenon that happens when a Cielioid is under great stress, or occasionally brought on by old age. They take root in the ground, and their skin turns woody, with branches growing out, rather like a tree. There is no known cure, but the Cielioid often retains some limited consciousness, and has a limited ability to hear and speak. Ceilioids who have gone to root will often live a longer lifespan, commonly surviving centuries in an immobile state.
Reproduction
The Cielioid reproductive system is sexual, but nearly all Cielioids are hermaphrodites. (Even so, self-pollination is rare.) The pods on their torsos are essentially large seeds, and families plant these seeds in communal "podding grounds".
Once a year (the year of the Cielioid home-world is around 500 Earth-days long) , adult Cielioids go into “Season”, when their pods are ready for pollination. This state is visibly apparent, because their skin changes coloration. This color change always happens in the area around the pods, but can extend over the entire body. The colors and patterns Cielioids take on during their Season are genetically determined, and vary greatly by individual. (as a result of this feature of their biology, Cielioids have a sexual reaction to tie-dyed t-shirts)
