Canopian (The Time Tunnel)

Canopians are a sapient humanoid species from the Canopus star system.

Biology
They look similar to Humans, except for their silver skin. They derive nourishment from photosynthesis, feeding on the light generated by their star, Canopus. At night, they become dormant and therefore more vulnerable.

Culture and society
Their technological achievements include advanced computer systems, time machines, bulletproof suits and energy weapons, among others.

History
In the year 8433, the Canopians made use of their time-travel technology to abduct Human beings from several time periods and extract their memories in order to study their culture. Among those who have been abducted by them are Marcus Tullius Cicero, Desiderius Erasmus, and Adolf Hitler.
