The Tammarians were a race of beings native to the planet Tammar. They have evolved a unique oxygen pouch in which they store oxygen for later use. This pouch served to provide the Tammarian with extra oxygen in the thin atmosphere of Tammar. When full, it also allowed a Tammarian to survive in the vacuum of space for a short time. Tammarians were deathly afraid of water, since they have little experience with it on Tammar.
