The Zevians are a amphibious humanoid species. The Zevians possess physiology common to amphibious species, including low light vision and excellent swimming skills. They stand an average of 1.8 meters, had smooth green, blue, or brown skin and large, lidless, black eyes.
Zevians possessed exceptional olfactory and pheromone sensing skills, enhanced by head-tresses. These tendrils are used to detect the emotional state of another being, but were most effective underwater. Within Zevian culture, the ability to sense pheromone changes was an essential part of the communication process. All Zevians had fourteen tentacles and multiple hearts, which were capable of beating separately.
