Vosans (physiological classification SNLU) are a sapient species of frigid, methane-based lifeforms which dwell in an environment with extremely cold temperatures and absolutely no radiation, not even starlight. They breathe methane and are similar to a crystalline starfish. Vosans cannot be exposed to any form of light or heat, as even the body heat of a single Human would be enough to kill all Vosans in the room. As such, each species must use isolating vehicles when visiting the other's environment. Any temperature above minus 120 degrees is deadly for a Vosan. This species is a member of the Galactic Federation.
