[ WP ] Describe to me an alien race physically , culturally , and the state of affairs on their world .

I'm writing a story about an alien race: 
 The Planet - 
 
 A tidally locked, large planet. The back of the planet is covered in a single giant glacier. The part facing the suns is swamp-like around the outer edge, as it gets regular run off from the glacier as because of the elliptical orbit. And the central part is extremely dry and sandy. The entire planet is very hot. 
 
 
 Physical characteristics in human terms ( I use analogous structures to describe the body parts where that can be done. ) - 
 
 The species has a range of heights with between 7.5 and 10 ft tall being within the normal ranges. They vary in color from white to black with shades of blue-grey in the middle. This is from a combinations of cyanide and iron in the outer layers of their skin. 
 
 They are thin and flat, with no fat to speak of. They have heavy, calcified plating attached to their spines that protects their backs, necks and heads. It's articulated and lays in layers. It's used both in defense and for digging purposes. Their earlier ancestors used their bodies to burrow and the plating can be used to ripple loosened sand and sediment back. 
 
 Under the plating is thin skin that covers their external resp o-circulatory system. A deeper, inner system delivers oxygen and nutrients to a gelatin-like storage ( Kortimi ) that releases it to the body as there is a demand. The bulk of the ( kortimi ) is under the plating but there is some around the organs and along the front of their bodies and limbs. 
 
 They have four long and very flexible limbs. The limbs are thin to facilitate digging. The limbs are primarily bone, tendon, and skin. The bulk of the muscular work is done in the torso and proximal to the torso in the limbs. 
 
 They have eyes that are always open and require a lot of light ( by human standards ) to see. They are set into the face and covered in a hard, clear lens. The reason for that is their sun always being `` up.'' They navigate closed, dark spaces by sonar. 
 
 The face is a flattish curve. It leads the body when burrowing. The mouth is double hinged. Large, needle-like teeth fit closely together and are the main feature of the face. They are omnivores and are just as likely to chew through deep-grown roots as they are to eat lower species. 
 
 There are no external sexual characteristics but there are three sexes. The topic only comes up when they're talking about children. The male of the species is universal but there are Swampland-females and desert-females. One carries children internally and another plants them externally. Externally is traditionally more acceptable making desert-females a more ideal mate. 
 
 Sexual maturity is characterized by a hardening of the plating on the back ( which continues to be worn down and grow through adulthood ) and a complete shedding of the skin which is extremely uncomfortable. The shedding also primes the immune system.

 Culturally - 
 
 There are four main classes in Tuaboz society: 
 
 Creators: Who study the sciences and make all the advances. They spend great deals of time observing applicators and devising ways things can be done better. 
 
 Applicators: Who take what the creators invent and perfect it. They do all the `` work'' of life. 
 
 Entertainers: Who dedicate all their time to doing things beautifully and learning all the arts. They are also the masters of ceremonies and are centerpieces of any gathering. Sometimes literally. 
 
 Children: Children are raised communally by Applicators who work in the field of childcare. 
 
 Children are held in low regard. It's expected that after conception, thirty percent will never live, and forty percent of the ones that are born wo n't reach adulthood. Value comes with joining one of the other three classes. Children that die are discarded and recycled with no ceremony. 
 
 Children split themselves into natural groups at a young age. Carers make sure they learn all the factual information they need and teach the groups to interact in a very strict way and to be uncomfortable with anything less. 
 
 After sexual maturity, which varies from child to child, they are able to take apprenticeships and find their place. 15 - 20 % will be Creators, 70 % will be applicators and 10 - 15 % will be suitable for Entertainer status. Entertainer status is further broken down into `` Performers'' and `` Facilitators'' with only the most beautiful and perfectly formed becoming Performers. Each performer can expect to have eight to ten personal attendants. 
 
 Culturally, there are three rights of passage into adulthood. They often have chosen their living-partners by the time they reach puberty. Before leaving child-care, they have to register as individuals with the government with the names they have chosen or been given. They have to attend a show by the entertainers. And they are given information of their biological parents so they can predict for any future illness or concerns. Siblings sometimes contact each other on learning they are related just because they can, but hardly anyone meets their parents. 
 
 Their society is very collective. A good life is one of service. They work to be extremely efficient. They live in large, tightly knit groups, usually split along lines of who they got along with in childcare. A performer will usually live with all their attendants and any friends they have. Teams of creators and applicators generally also live together if they do n't have other arrangements. There are no work schedules except those set by teams. The planet does n't experience day/night cycles. People work when they are awake and have the energy. 
 
 When society became more structured, timing became necessary. The year is split into four seasons ( Two hot, two cold ) because of the elliptical orbit. Each season is split into 8 `` months.'' and each month into 16 `` days.'' Each day has 1024 `` minutes.'' These are only really used to schedule things between parties. 
 
 The thought process is extremely literal. They do n't have imagination at all and they have no words for imaginary things. There are lies and there is some concept of lies that are impossible, but it's limited and only used for games among adults. A brainteaser of sorts. 
 
 Interactions among ones living-partners and strangers is extremely different. People who live together create their own culture in their homes. They are very open with how they feel and spend great amounts of time talking about it. When strangers meet, the actions are extremely formal and regimented. It's extremely rare that anyone is invited to anyone else's house or work. The only exception being people working in applications that provide an in-house service. Usually the entire household will leave so the work can be done. 
 
 They often do things because they can. The main characters of the story are on a ship that left the planet 700 earth-years earlier. They left to see what their moon was. Then they took notice of other planets and went to see those. And then they kept going. They find Earth because they were wandering in that direction anyway, hit some early radio waves scattered to space, and followed. They never thought to go back to the planet even after they lost contact, because the ship was self-sustaining and they were able to continue was reason enough to go. 
 
 _____________________________________________ 
 
 The habitable half of the planet is peppered with densely populated cities. The population is stable, neither rising or falling, because it's tightly controlled. The cities do n't communicate much except in a few specific scenarios: 
 
 Childcare workers rotate each season to ensure children are getting uniform, unaltered instruction. Creators communicate to each other through a huge `` internet.'' When they discover a better way to do something. They suggest it and other creators can decide whether or not it'd be wise to implement it into their own city. 
 
 Entertainers travel with their attendants three times a year to a large, centeral ceremony. And twice a year to internal competitions that no one outside their group sees. 
 
 Outside of that, there is minor amounts of trade between cities and sometimes resources will be pooled for extremely large projects.

 WOW. I am sorry that is so long. I left out most the details. If you have any questions, shoot. I also have a language made for them and a writing system. I am working on a computer font I can use, but it's proving difficult.
