The Menk are one of two native species on the planet Valakis. They share the planet with the more advanced Valakians. The Menk are far less evolved then the Valakians, who treat them as lower individuals. However, the Valakians provide the Menk with food, clothing, and other needs.
Humanity conducted first contact with the Menk in 2151, when the Enterprise picked up a Valakian spacecraft and returned them to their homeworld, where it was discovered that a genetic disorder was slowly wiping the Valakians out. When Dr. Phlox was asked to help, he had a hunch the answer might be in the Menk's immunity to it. His thoughts were correct, but they also found that the Menk were on the verge of an evolutionary breakthrough, showing signs of increased intelligence, which might lead to them becoming the dominant species of the planet.
The universal translator was unable to translate the Menk language as of 2151. (ENT: "Dear Doctor")

The unnamed Menk assisted Dr. Phlox in his efforts to find a cure for the disease that was killing the Valakians. He let Phlox do a bio-scan on him. When he asked what Phlox was doing, Hoshi told him, that the doctor was looking inside him. (ENT: "Dear Doctor")
