Ants are the decendants of the ship's evolved lab ants or Titanomyrma sapiens and have set up shops all along the Red Dwarf's Promenade in an alternate reality. The shops offer a variety of services such as dinning, pubs, game centers, clothing repair, trinket repair and resale shops. The ants didn't keep very good history on their race since survival was their first concern untill they were able to get a strong hold on the ships trade center. Once the ants were established they had a strong period of growth before the crew began to awaken.
