The Acamarians are a humanoid species from the planet, Acamar III in the Alpha Quadrant. A segment within the population was known as the Gatherers. They had split from the rest of the society to live a nomadic lifestyle, raiding outposts and starships. After successful negotiations between the Gatherers and the rest of the Acamarians saw the Gatherers reintegrated into the society in 2366. (TNG: "The Vengeance Factor"
They were recognisable by a formed indentation on their foreheads and by the traditional tattooing on their faces. These tattoos were often clan related to help identify a person's clan. It had decreased in popularity in the later 24th century, though the Gatherers still practised it heavily.
