Trulgovians are a spacefaring species. They possess bullet-shaped bodies and three arms and three legs. Trulgovians are known for being natural miners, as they prefer to be underground. The Trulgovians maintain economic links with the Ferengi and have been known to purchase starships from them.

In 2370, the Trulgovian freighter Cl'mntin docked at Deep Space 9 after having spent several weeks mining keithorpheum. Some of the material stuck to their clothes and was brought aboard the station. (DS9 novel: Cardassian Imps)
