Society and culture
Iyaarans reproduce by post-cellular compounding, and emerge full-grown from natal pods. They regard the consumption of food as being for sustenance only, and their diet is bland in the extreme by the standards of many other humanoids. Iyaarans have no natural understanding or social forum for concepts such as pleasure, antagonism, love, or crime.
The Iyaarans conducted their first cultural exchange with the Federation in 2370. During the exchange they explored certain concepts by assigning an ambassador to each. While Ambassadors Loquel and Byleth succeeded in their studies of pleasure and antagonism, Ambassador Voval felt he failed to understand the nature of love. (TNG: "Liaisons")
