Balanites aegyptiaca
In the Sahara, 332 plant species have been recorded as food plants of the dromedary. These include "Aristida pungens", "Acacia tortilis", "Panicum turgidum", "Launaea arborescens" and "Balanites aegyptiaca". The dromedary eats "Acacia", "Atriplex" and "Salsola" when they are available. Feral dromedaries in Australia prefer "Trichodesma zeylanicum" and "Euphorbia tannensis". In India, dromedaries are fed with forage plants such as "Vigna aconitifolia", "V. mungo", "Cyamopsis tetragonolaba", "Melilotus parviflora", "Eruca sativa", "Trifolium" species and "Brassica campestris". Dromedaries keep their mouths open while chewing thorny food. They use their lips to grasp the food and chew each bite 40 to 50 times. Its long eyelashes, eyebrows, lockable nostrils, caudal opening of the prepuce and a relatively small vulva help the camel avoid injuries, especially while feeding. They graze for 8–12 hours per day and ruminate for an equal amount of time.
