Karnasaurs are a highly intelligent species saurian in appearance. They were once thought to be extinct until the Galactic Senate discovered new factions in the Scutum-Centaurus Arm such as the Sacred Federation of the Praetori.

Physiology

Karnasaurs are relatively humanoid and possess four limbs: two arms and two legs. However, their mouth is animalistic in appearance consisting of long jaws, and their skin appears black. They seem to lack scales, and their body temperature remains about the same, leaving most to see them as mammals. The fact remains, though, that are indeed cold-blooded, however their micro-scales are specially evolved for thier homeworld, Karnas', varying temperatures.

Their eyes are grey with a yellow iris which are adept to vision at night. Karnasaurs evolved as a mid-tier carnivore; they were prey to some of Karnas's larger creatures for a long time, and thus evolved eyes on the sides of their head at a position to allow for practical binocular vision as well as wide peripheral vision.

Heating System

Unlike other reptiles' scales, Karnasaur micro-scales are so small, they seem to have a dangly, tough hide. However, the scales can dilate, or relax and grow larger, or tensify and shrink, according to the Karnasaur's tempratural needs. Heat builds in an air bubble below the skin, making the Karnasaur blow up like a balloon, if it is not released when the scales tensify. Unlike mammals, Karnasaurs cannot sweat, so hot skin is an issue. As such, Karnasaurs must cool down their skin after a while, or face heat exhaustion.

Intagumentary System

A Karnasaurs skin comprises of micro-scales, designed for Karnas' hot summers and cold winters. There are no blood vessels in the micro-scales, however, the micro-scale cells can produce their own nutrients via digesting cellulose. This piece of DNA is restricted to the skin alone, and it is illegal to allow any other cells to be given this gene. Due to a lack of melanin, Karnasaurs can't tan, and due to a certain DNA bonding chemical, they can't burn.

Immune System

Karnasaurs have a standard immune system that targets alien invaders and destroys them, as a human's does. Due to the lack of blood in the skin, Karnasaurs have a blood clotting agent that works very quickly on the inside of their bodies, and can be administered to other species as a way to quickly thwart internal bleeding in minutes. The Karnasaurs immune system goes one stem further though: It targets anything without recognizable DNA. This means Karnasaurs make it through cancer and genetic disorders unless the problem is highly severe. This also means that transplants, unless cloned healthfully, will always be rejected. However, transplants are rarely needed, as Karnasaur medical techniques usually succeed, if the immune system doesn't.

Cardiovascualar System

The Karnasaurs use a 4-chamber heart. Karnasaurs breathe nitrogen, the dominant gas in most inhabited/habitable worlds. Because of this, Karnasaurs feel invigorated and alive on many worlds not their own. Since Karnasaurs are nirtogen based, they give off a waste gas of pure nitrate. This is because nitrogen in their body bonds with the nirtogen it is fed, creating a pure nitrate that Karnasaurs can breath. This can also mean that Karnasaurs have a sort of breath weapon, as any species who breathe oxygen that inhale it will grow a bad coloration and eventually asphyxiate. This also means oxygen breathing species can cause Karnasaurs to asphyxiate.

Digestive System

Karnasaurs are carnivorous, and as such they cannot digest fruits and vegetables. Due to this, Karnasaurs lack plantations, and rely on barns for food. Surprisingly, Karnasaurs don't eat their pets. When the meat tissue is broken down to simpler components, the Karnasaur swallows down the chime down their esophagus to their stomach, where the acids that are specially built to get the most out of the meat break it down further to mere nutrients and waste. After approximately four hours in the stomach, the food goes down into the small intestines, where the nutrients are absorbed into the body. Once it hits the large intestines, all that's left is soupy waste. As it moves through the colons, the waste is once again refined to get the trace amounts of nutrients left, and the water is removed, turning it into hard feces to be expelled at the rectum.

Maturity cycle

Unusually, Karnasaurs age rather slowly which was an adaption towards their hostile environment. Hatchlings gained hunting and hiding skills early on to assist the pack as a whole from birth, since the pack needed the help during the day. Albeit, mothers kept close eye on the hatchlings and wrymlings, but every member of the pack was expected to hunt, in a pre-frontal cortex social aspect kind of way.

1. Egg for about a year

2. Hatchling for the first 3 years. Hatchlings are born with the ability to eat solids and learn to walk and talk during this time.

3. Wrymling: from 3-10. This is the time when youths learn to fly and recieve basic, formal education from age 4-5

4. Wrym: from 10-20. This is the time equivalent to upper teen years. Wryms become sexually active (ergo the cultural requirement to find a mate at this time) and diverge sexually. Males gain muscle mass and a new set of claws and teeth, along with deepened voices. Females grow more curvy as a result of the reproduction system becoming more biologically demanding, along with increased flexibility (they evolved having to care for the young and search for prey simultaneously).

5. Youngling: from 20-30. This is a young adult stage. Younglings have an adventurous mind and typically work as soldiers, explorers, traders, etc, anything that means lots of sights. Since they're mated at this point, they typically work with their mates and move as a couple.

6. Adult: from 30-79. After a century or so, a youngling pair will grow tired of adventuring and settle down in a more stable, stationary position and find a home. They will also begin raising a family of their own at this point, typically around the late 30s. By the 50s, they will see drastic biological breakdown from their younger days; Females lose their curves and become stiff, males start loosing muscle mass, and both genders see a loss of sexual potency; Equivalent to menopause or ED.

7. Elder: from 80-Death. Elders are the old people of Sauren society. They usually retire to a private location, many are rather wealthy, and a few start careers in politics to sail out their last years. Elders from all genders see biological breakdown at an accelerated scale. Though Karnasaurs don't suffer from arthritis as we know it, the past few centuries will take their toll on joint functionality. In addition, elders see a lose of muscle strength, eyesight, hearing, mobility, and learning rate. Still, as a race of hunters, elders are much more capable than most human retirees.

Primal history

During the Sauren primal age, Karnasaurs were actually far down the food chain a good while. They mainly existed in a large valley near Sauris, where it was so thickly vegetated and so protected by mountains, it was an eternal night. Karnasaurs, adapted for such darkness, thrived here, but those who left were easily spotted by predators adapted for light.

However, an asteroid that is now Karnas' moon caused a gravitational event that altered Karnas' tilt, causing night cycles to increase permanently with decreased day cycles. The Karnasaurs thrived in the new, elongated nights, and became the dominant predator across the continent as a result.
