Colo

A Colo as they appear in the Halo Encyclopedia (2022 edition).

"Your father was a filthy colo and your mother was a hole in the wall!"

— A sexual insult in Sangheili culture

The colo is an animal that is farmed across Sanghelios for its meat. Healthy colo are said to have long, glossy coats.

Although indigenous to Sanghelios, the Office of Naval Intelligence was able to import some of the animals to ONI Research Facility Trevelyan, to be bred for their meat. The colo grown on Trevelyan were genetically modified by ONI's bioweapons team to make them indigestible to Sangheili, and would have been used to starve Sanghelios' population if ONI's program of internal dissent did not succeed. The meat of these genetically modified colo was given to Jul 'Mdama during his imprisonment at Trevelyan, to test the effects of the now poisonous meat.

On Earth, human authorities permitted a supplier to acquire and distribute ordinary colo meat and other basic Sangheili ingredients to ex-Covenant asylum seekers in Rio de Janeiro to accommodate their alien diet. The Sangheili residents who settled in the Sekibo district of the city created a fusion of Earth food and alien cuisine, crafting their own version of Rio's traditional feijoada stew using colo meat and Subanese spices. Around 2558, while penning his biography, Rendezvous with Ramen, renowned chef and food critic Arturo Bustamante visited a Sangheili-owned restaurant in the district and experienced the colo-infused feijoada among a variety of other delicacies.
