===Anatomy and physiology===
Like the majority of the League races, the Skurians are a bipedal humanoid species consisting of a torso, two arms, two legs, and a head connected to the torso by a neck. They share the same physical characteristics found in the fellow humanoid species of the League, that being the possession of a nervous, cardiovascular, circulatory, digestive, endocrine, immune, integumentary, lymphatic, musculoskeletal, reproductive, respiratory, and urinary system. Skurians are relatively hairless as a species, with the hair on their heads and eyebrows being the only hair known to grow on their bodies. The species universally possesses black hair and green eyes, and have bright red skin for which the Skurians derived their name.
The skin of a Skurian is naturally insulated for protection against the cold temperatures on their homeworld, and features a degree of thermo-regulation rarely found in fur-less animals and humanoids of their size and weight. Skurians are capable of surviving in regions and planets where temperatures frequently jump between sub-zero to blazing within the span of a few months, with their insulated bodies protecting them from the rapid changes of temperature, and allowing them to adapt to the new climate of their area. This trait has allowed the Skurians to survive on the Martian planets they inhabit, where the temperature can drop to less than -100 °C (-148 °F) during the winter months. Working along with this natural dermal insulation, Skurian blood functions as an antifreeze with the possession of ice structuring proteins (ISPs), which inhibit the growth of ice crystals in the blood, and the recrystallization of ice that would prove fatal if allowed to happen. This allows the Skurians to function comfortably in cold weather with little protection from the frost surrounding them. Being native to a worlds with high-copper content, Skurian blood possesses the copper-based protein hemocyanin, which has the resulting effect of causing their blood to appear green in coloration.
Line 10:
As a direct consequence of their civilization developing on a low-gravity planet, the Skurians are generally taller as a species compared to their fellow League citizens. Both sexes of the species possess a drastic height advantage over other humanoids of the League, with the average height of a Skurian male being 218 cm (7 ft 2 in), while that of Skurian females being approximately 210 cm (6 ft 10 1⁄2 in) on average. Due to the rigid nature of the species' bone structure, height shrinkage with aging is a rare occurrence for the Skurians, even on high-gravity worlds, and common only in the youth of the population whose bones have not fully solidified during puberty. This is a double-edged sword however, as bone damage in a Skurian is likely to have more adverse affects as it takes far longer for their bones to heal, and the rigidness of their bones results in a degree of brittleness that can cause Skurian bones to shatter rather than crack if enough damage is done. The overall mass of a Skurian is typically 47–56 kg (104–123 lb) for males and 33–42 kg (73–93 lb) for females. As a rule, the weight of a Skurian is not as heavily influenced by environment as in other species, with diet and physical activity playing a more direct role in the differences between individual Skurians.
