Well I've accumulated quite a few alien species over time and well I thought it'd be a nice idea to make a thread sharing information on all of them. Perhaps use this to set up an RP using the setting later on. I'll use the pics on my DA page so it'll be more reliable. Well with that in mind lets get started.
SokueFirstly we have the Sokue. There race live aboard massive colonies usually build in orbit around gas giants. The colonies have earth level gravity and atmosphere as well. A good portion of the colonies have forest and natural terrain as well as cities here and there. The Sokue occupy no known worlds. There own home world was destroyed half a billion years ago. Since then they have master interstellar and it is believed intergalactic travel.

Most of there technology is biological in nature. They are capable of eating like most beings but however can get by on photosynthesis alone for a while if need be. There kind even has a natural ability to manipulate light. As you might guess they do not like the dark. It can drive them insane as certain key chemicals are no produced in the absence of sunlight. This causes what they call "Nocturn Madness."
http://lig28.deviantart.com/art/Kawa-of-the-Florkata-77481026SokeeThey're a mono gender species with biology between reptiles and mammals. They're warm blooded and have hair on there heads and have soft scales that from a distance can pass for mammalian skin. They're average life span is 370 to 400 years of age. They're considered adults at 100. Unlike humans there aging stops at it's physical peek and then somewhere around the age 320 they begin to slowly regress although they do retain there knowledge. An "Elder" can be differentiated from actual children by hair color. "Elders" have very light blond hair. Normal hair color range is Red, brown, black green, and blue. Oh fun fact the birthing parent is referred to as Moda and the non birthing parent Doda. Sokee technology is a mix of Roman level tech and modern day. They have a saying. "Technology should mimic and emulate nature and life. Never Hinder it."
http://lig28.deviantart.com/art/Kibou-the-Sokee-90474511YabunThey live on a world that orbits a white dwarf star. Thanks to the planet's atmosphere though it's fairly warm. His kind live in rain forest areas, cliff faces and caves. They are very accustomed to the dark and don't like bright light. Since there eyes are accustomed to lower light levels bright like like humans are used to can be very damaging to there eyes. Cultural wise his species are very communal and social. They hate being alone. However they are shy and wary around outsiders.
http://lig28.deviantart.com/art/Yen-the-Yabun-93731077KeetarThe species is distantly descended from insects. They have a similar reproductive and cast system. You have four diffrent cast. Royal Females. These are the ones that are capable of reproduction. Drone Females. They can't reproduce but still have powerful maternal instincts like the Royals do. These females take care of the brunt of the Royal's many thousand of offspring. Next we have the Royal Males. Once more they're the ones that reproduce. They have strong parental instincts as well but not on the same level as females. Lastly we have drone males. They don't reproduce and on top of that don't age beyond there equivalent of mid to early teens. Sometimes sooner. They are often very bright. To them whatever they study or do for work is play. Developing astrophysics is just play to them. These ones also provide females with an outlet for there maternal instincts.

http://lig28.deviantart.com/art/Dokeen-the-Drone-99829421SauriansThey are one of two surviving sentient species living on Earth. Saurians are highly intelligent beings. Saurians come in a great variety. Scale color and patterns vary widely as well as feather color and distribution. Some are covered in feathers even. Some have more pronounced muzzles, some have beaks, some have killing claws like Raptors, some have shorter tails and some have none at all. There species is derived from nearly a dozen diffrent sentient saurian species. However all are now considered one as they are able to reproduce between each other to produce viable offspring. This in part contributes to the extreme variation between individuals. Females are the more dominant gender however and males have more bright and decorative colored feathers.

http://lig28.deviantart.com/art/Father-and-Son-s-Day-Out-103864807NeanderthalThey are the second of the two surviving Terran species. They evolved alongside humans. However unlike humans they had more of an affinity for the world around them as well as heightened intelligence. Neanderthals also possessed superb fine motor skills. They were also significantly less violent. These traits were respected by the Saurians who by now had a thriving civilization already set up. When humans arrived in Europe they were quick to come into conflict with the Neanderthals. However this unprovoked aggression was met swiftly by the Neanderthals and Saurians. Humans were driven back to Africa. As luck would have it they went back just in time for a severe drought. Human numbers already diminished they fell into extinction.
http://lig28.deviantart.com/art/Calnen-the-Neanderthal-106801979VocaranThey live on a world with two suns and two moons. As such they having a saying. " A Vocar can no more live alone then the suns or moons. One may survive but he cannot live." They are very communal and have a variety of ceremonies for diffrent occasions, most of which involve song and dance. They are powerful warriors with keen senses. They also have a powerful sense of honor. They once had a very violent past. You'll find more fallen kingdoms in there history then anywhere else. That violent past is what has taught them the value of life and made them the peaceful honorable warriors they are today.
http://lig28.deviantart.com/art/Noble-104901113Akawash.There kind are amphibians native to Akawan. There world has a diffrent atmospheric composition then most and off worlders need to take a day or so to adapt to it. Because of this the water is also slightly diffrent as well. It is drinkable by off worlders though. But the AKawash are so adapted to there own atmosphere and water they can't survive without it. Regular water and air will not sustain them for very long. Because of this there kind have colonized no other worlds and only have a few space stations in orbit. However the stations are very large and contain large quantities of air and water from the planet below which are sustained by a replication of the ecosystem on the planet below. Despite this however there world is a buzz of trading. The water when filtered through certain plant life on there world has medicinal properties. There world has only three large continents and vast oceans peppered with islands.
http://lig28.deviantart.com/art/Abune-The-Akawash-105090336Spacialarevolved in a rather odd habitat. A small asteroid field which had just enough gravity to hold enough of an atmosphere to have some liquid water. The Spacialar are a very hardy species able to withstand extreme temperature variation. They can survive in even the vacuum of space. They don't have a respiratory system as the atmosphere there was at a premium and hopping to asteroids outside the atmospheric area was common. As such they don't breath. Even the sun's radiation doesn't harm them at all. In fact they use it to there benefit. The partial green color of there skin is due to a type of chlorophyll in there bodies. They do eat but can survive without doing so for a very long time. As for locomotion they jump from asteroid to asteroid but can also use a form of telekinesis for powered flight. However they can get around very easily on planets with even higher gravity then earth. Another fun fact is that they have no native spoken language as they primarily live in the near vacuum of space. Their primary means of communication is telepathy. Spacialars are a very common sight now in the galaxy now having spread out quite a bit.
http://lig28.deviantart.com/art/Auros-the-Spacialar-106082610Artificial Life FormsThere are a vast variety of them in the galaxy coming in all shapes and sizes. From A.I.s aboard starships or stations to androids and various other robots. Although they hold no one world as there homeworld they are now recognized as a sentient species and as such have full rights as any flesh and blood being. Some are quite friendly with biological lifeforms while others are extremely xenophobic of them. This depends on the individual's background with biological beings which in some cases has not been pleasant.
