Martian (Evolution on Mars)

Martians are the native sapient inhabitants of the planet Mars.

Biology
Martians are tall bipeds, over 10 ft tall, with disproportionately enlarged chests that allow them to survive in a rarefied atmosphere, and bodies covered in white fur that protects them from the cold. Their feet are shaped like suction pads and equipped with valve openings. They have an elephantine trunk, horizontal eyestalks, large shell-shaped ears, and a pair of antennae with which they communicate by telepathy. The trunk and eyestalks are also retractable, in order to shield the eyes and nose from the cold when needed. Their intelligence is keenly developed.

Culture and society
Martians are an ancient, scientifically advanced race. Their technology includes atomic weapons, synthetic pellets containing food and water to help them survive in the desert, and electrically-warmed clothes.
