Malurians were reptilian humanoids with grey, scaly skin that covered their bodies. Females were much larger than males and stayed on Malur, with each female taking a number of male Malurians as mates. Most males were also content to remain on the homeworld near their mates, however some were inclined to leave and explore the galaxy. Malurian males had no sexual interests with mammals, and mated for life with a single female. (ENT - Rise of the Federation novel: A Choice of Futures)
