Herbivore referred to species that consumed plant-based foods. Examples of herbivores included the o'cerry.[2]
Omnivore referred to species that subsisted on both animal tissue and plant-based foods. The tauntauns of Hoth were omnivorous, primarily eating fungi and lichens, though they also ate smaller animals when necessary.
Ergovore referred to species that sought out and fed upon pure energy. Business owners sometimes enhanced their security by using these creatures as a way to keep firearms out of their establishments. Salla C'airam lined the entrance tunnel of his high-class cantina with underfed ergovores so that they could detect any hidden power sources or other high-tech weapons.[3]
