Creature:Sintan

The Sintans are red turtle-like mammals that developed on the planet Sortep.

Evolution
The Sintans developed from the Presintan species. They developed in a shorter time than most creatures because of the high radiation in Sortep. Shortly after developing brain, a spaceship containing various chemicals crashed on Sortep. Many of the chemicals were mutagens, and caused the Sintans to evolve even more quickly. In the thirty thousand years after the spaceship crashed, three different main mutations appeared:

Winged Sintans
The Winged Sintans are slightly smaller than the average Sintan, winged, green, and very noticable. They developed on the South part of the main continent.

Runner Sintans
The Runner Sintans developed another pair of legs and have hooves instead of feet. They move in double the speed of the average Sintan. Their color is orange. Together with the Four Handed Sintans, they drive the Sintans' spaceships, due to their ability to use six pedals instead of four.

Four Handed Sintans
The Four Handed Sintans are blue, striped Sintans who developed another set of arms. They are mostly spaceship drivers and artists, and can use each of their four hands equally well.

Anatomy
The Sintans have a hard armor on their backs to protect them from boulders flying in the strong wind of Sortep. The armor consists of four plates made of dead cells reinforced with bone. The front part of the armor is covered by poisonous spikes.

Intercellular Structure
Due to Sortep's radioactivity, the Sintans have developed very quick DNA repair systems, allowing them to survive in 15,000 Gy (a measure of radiation), while 10 Gy is enough to kill a human being. The Sintans' cells use uranium in addition to ATP to store large amounts of energy.

Differences Between Genders
When a Sintan female is pregnant, there are 30-40 fetuses inside her womb. Because of that, Sintan females are stonger and larger than males. Their scales are slightly lighter red than the males' and they move faster, but they are a little less agile.

Other Interesting Facts

 * When a Sintan corpse reaches the rigor mortis stage, the uranium stabilization proteins break and create a nuclear chain reaction that causes the dead Sintan's corpse to explode.


 * Due to the high percent of uranium in Sintans' bodies, they are poisonous, and a Sintan's bite can poison creatures from other planets.


 * Sintans need to eat uranium to survive, and they are constantly searching for uranium containing planets for a food source, in addition to the energy source.


 * Cutting a Sintan's armour produces a loud screech.
