Colo

Colo is an animal that is farmed across Sanghelios for its meat. ONI was able to acquire some, which was given to Jul 'Mdama during his imprisonment at ONI Research Facility Trevelyan. ONI had some imported to the Shield World so they could breed them there. Healthy Colo are said to have long, glossy coats. The Colo grown on Trevelyan were genetically modified to make them indigestible to Sangheili. These Colo would have been used to starve Sanghelios' population if ONI's program of internal dissent did not succeed.
