The Porcion are fish-like amphibious humanoids with domed heads, webbed hands, and large eyes. Most Porcion had salmon-colored skin, often mottled with light and dark patterns, though examples of other skin colors were known. They could also descend to depths of up to 30 meters below sea level without breathing, though they found it uncomfortable and often used organic gills. Porcion could stay underwater for a long period of time, although a frightened Porcion, particularly a juvenile, could drown underwater. They also did not need to decompress when resurfacing.
Porcion could swivel their eyes independently from one another, focusing on two areas at once. Porcion saw in different wavelengths than Humans, making it difficult for one species to view visuals designed for the other and vice versa. Their eyes were often used to express emotion; staring with the left eye was a way of showing surprise, while staring with the right eye was either a challenge to fight or an expression of love, depending on the circumstances.
The Porcion had developed a very civilized culture. Art, music, literature, and science showed a creativity surpassed by few in the Quadrant. The Porcion literature depicted stars as islands in a galactic sea. This showed a passionate longing to explore space and discover other civilizations.
The Porcion tend to dislike and mistrust smugglers.
The Porcion are one of two species from a planet where the Fen Domar attacked. They were brought to earth and its colonies.
