Creature:Miigishmoter

The Miigishmoteren are silicon based creatures that live underground in the planet Miigish. They use hydrogen sulfide as a substitute for water and oxygen. Their respiration works by breathing in gaseous H2S and eating substances containing polysilane chains. The H2S and polysilanes are then reacted to form silicon sulfide, which precipitates as solid waste, and hydrogen gas, which is then exhaled. They don't use hemoglobin or any direct analogue that would bind to oxygen. Instead, they use an acid that would bind to the lone electron pairs of H2S. Thus, their blood is not red, but white.

Their homeworld, Miigish, has an inhospitable surface. It is close to their sun, and has little to no atmosphere. The caves underground provide a much cooler environment and contain the necessary gasses for their biochemistry.

Due to their alternate biochemistry, the Miigishmoter are unable to directly interact with other races of normal carbon based life. The polysilanes that compose many of the Miigishmoter's biochemicals easily combust in the presence of oxygen. Also, the H2S that they use as a life solvent is liquid at temperatures below -60 degrees C.

The Miigishmoter have white skin, 2 arms, 2 legs, and 2 fingers and a thumb on each hand. Their eyes have white pupils and colored sclera. On their heads, they have distinct markings that are unique to each individual. The color of their markings and of their sclera match.

Miigishmoter are able to see into the range of infrared light and UV light. Due to the conditions of their planet's surface, the Miigishmoter stayed underground during the course of their evolution. Seeing the colors of infrared and ultraviolet come from the surface served as a device to make sure they never wandered too far up. As a result, colors of low frequency and high frequency became associated with fearful connotations.
