A mustelid species from the Star Wars Legends continuity, first appearing in the Star Wars comic Gambler's World, and later identified by name in the novel Ambush on Corellia. Sharing the Corellian system with humans, the Selonian race is very close-knit, almost to the point where they function like eusocial insects rather than individuals. Females make up 99% of the population, with only 1 out of every 100 born Selonians being male. Their closeness is such that dishonesty is as criminal as murder, though some Selonians are known to leave society to live as individuals.
