Durgolosks were a non-sentient, six-legged species of fearsome predators native to the swamps of the planet Barab I. Members of the species were huge and white and brown in color. They also possessed tentacles that were tipped with venom. Durgolosks spent more time sleeping than hunting but ate any creature they met when they did hunt. The Barabel species, which was also native to Barab I, considered the slaying of a durgolosk to be an impressive achievement.
