The Lenarians are a humanoid species from the planet Lenar. Lenarians are typically polygamous, where a man typically has three wives, who each have three husbands. In addition, Lenarian marriages are not exclusive, and married Lenarians can be intimate with anyone they choose. The females emit powerful pheromones during their mating season. Male Lenarians often become combative during this time, and mating can require medical supervision. Lenarians typically prefer to be amongst large groups and find solitude uncomfortable. However, Lenarians, at least males, are uncomfortable being touched by persons they are not intimate with. On their homeworld Lenar, the 12 billion Lenarian inhabitants all share one continent, with the result that living-space is at a premium and Lenarian culture has come to embrace close, communal lifestyles. Though this habitation arrangement is due to choice rather than necessity. Lenarians have prominent facial ridges running down either side of the forehead to the cheeks, an enlarged brow ridge under a high receding hairline, a vertical crevice in the center of the forehead and a ridged chin. They also have ridges on their back, along the spine. Their toenails are dark brown and yellow striped, and they grow so rapidly that they must be groomed once a week. Lenarians also have very long tongues, and they use tongue scrapers. Lenarian males have a line of hair down the middle of their chest, up to their throat. In 2440, 11 Billion were transported to Earth space due to over population.
