The Xyol (Vaccomo Sapiens) are e xenophilic species that founded and controlled the First and Second People's Republic of F'omol. They hail from the world of F'omol a ecumenopolis with many layers.
Features
The Xyol host a humanoid body, with two curled horns on the top of their snake-like head. They commonly have a muscular body, with leathery skin and purple marks. They stand on average 240 centimetres high, and weighing (in 1G) 390 kilograms. They have four fingers on each hand, and three toes on each foot. The Xyol have three genders, male, female, and bi-gendered.
History
The Xyol have had a turbulent history, with the first glimmers of sentience arising just over a million years ago. From there, it only took them a thousand years to achieve starflight, and founded the First People's Republic of F'omol. They lived a hedonistic lifestyle for nine-hundred-thousand years, and then their civilization fell. They arose once more, scattered on many worlds, to unite and form the Second People's Republic of F'omol. From there, they have fought in many wars such as the Succession of Tarmalyula and the Crusade of the Remone.
Biology
Digestive System
The Xyolian digestive system starts at the mouth, like most other humanoid species. They have no teeth, and so swallow whatever comes into their mouth that is edible. It slides or falls down a cavernous oesophagus into a gigantic first stomach. The first stomach softens the food, turns it into a slurry, and leeches all the water out of it. It then passes through into the second stomach, which digests the food. It breaks it down into proteins, carbohydrates and sugars, and then passes the unusable stuff into a storage chamber located in their abdomen. When the storage chamber is full, which happens about once every two months, the Xyol defecates a large amount of faecal matter. The Xyolian digestive system is so efficient, that the average Xyol defecates only 2 tons of faeces in their lifetime, whereas a human produces 11-12 tons. And take into consideration that the average Xyol unmodified lifetime is six times as long as the average human unmodified lifetime.
Nervous System
The Xyolian Nervous system, laid ent to end, would reach 2000 kilometres. This is over double the total length of the average human's neurons, laid end to end. The neurons are mostly concentrated near the brain, which is located right behind the eyes of the Xyol. The Xyolian brain is slightly small, compared to its body size, a fact that the Xyol do not like to advertise. Other major centres of neurons include the arm and leg joints, elbow and knees, and major internal organs such as the heart, stomachs and lungs.
Respiratory and Circulatory Systems
Xyol inhale on average once every two seconds, though when in high-oxygen consumption activities (exercise) this can spike up to once every half-second. They also have a peculiar trick of inhaling through the nose and exhaling through the mouth, or vice-versa, at the same time. The nose and mouth are connected to different air pathways, each which only comes into contact with the other at the lungs. Oxygen is taken from the F'omolan Air and bonded into the Xyolian blood-equivalent, a copper-based liquid that is green and has the consistency of water, which is what it is primarily made out of. The blood is then circulated around the body, passing all organs and muscles, providing them with oxygen. It also takes their by product, Silcon Dioxide. The SO2, also known as sand, is in very small amounts, scattered throughout the nitrogen that is also being taken out of the body. No oxygen leaves the body when exhaling, making mouth to mouth respiration for Xyol impossible.
Skeletal and Muscular System
The Skeletal and Muscular systems of a Xyol are very similar to a Humans - with one exception. In Xyol, there is not just on spine, there are two spines, tightly interwoven.
