The Yridians were a warp capable race in the 24th century. They were regarded as information merchants and smugglers, and were generally considered devious and untrustworthy. Yridians were humanoids who were usually bald, others had black or brown curly hair. They had wrinkled skin. They also had large rodent-like pointy ears but small eyes and noses. All Yridians had an indented ridge running across the full length of their heads and extending down their nose. Most Yridians had no thumbs, and possessed only four fingers on each hand.
