Faantine

Faantines are native humanoids of Faant, a damp agricultural world under the control of the Klingon Empire. Faantines stand about 2.2 meters tall and have a slimy-skinned, as well as strange jawless mouths. Whether due to anatomy or simple disposition, the Faantines are creatures of little emotion. Nevertheless, they are devoted to their Klingon masters and even revere them as gods.

At some point in their history, the Faantines came into contact with the Orions. In fact, over the years, due to Faant's proximity to Orion space, a large number of Orion colonists have settled on the planet. Relations between the three races are tense at best. (The Orions: Book of Common Knowledge)
