Twi'lek (from Wookieepedia)
"Oh, yes. Wormheads. Twin tendrils off head. Females much yum-yum."
―Vilmarh Grahrk[src]
"The natural grace and exotic beauty of the female Twi'leks made them a popular target among slave traders. Slavery was the main currency of Ryloth, which was tolerated by the Galactic Republic.[20] Some saw it as a chance to make money by kidnapping or selling orphaned children, while others saw slavery as a way of saving children from growing up in Ryloth's harsh environment. A number of Twi'leks believed that slavery was an efficient way to proliferate their species and preserve their culture, as the Twi'leks lacked their own means of inter-planetary travel. Regardless of how it came about, many Twi'leks lived as slaves or entertainers and were considered status symbols, especially the females of rarer skin hues: the Rutian and Lethan Twi'leks. Twi'leks that managed to escape from captivity usually turned to a life of thievery or prostitution, with both genders making use of their powers of seduction."
