Inhabitants of Tammar, known as Tammarians, were a distinct species originating from the planet Tammar. Due to Tammar's thin atmosphere, Tammarians evolved with specialized air sacks, enabling them to endure brief exposures to the vacuum of space. A profound aversion to water was also characteristic of them, stemming from the complete absence of surface water on their home world. One example of a Tammarian is Ayddar Nylykerka.
