Although camels are sort of a taken for granted, ABC animal, domestic Bactrian camels can serve as animal ambassadors for wild Bactrian camels.
I do enjoy seeing dromedary camels contrasted next to Bactrian camels, personally, and I slightly prefer dromedaries.

Home to dromedary camels and a small group of Somali sheep, who have been added a few years ago. They have had lambs in the beginning, but the males have been transferred to sister park Planckendael, where they live with the Ankole-Watusi herd. With lion enclosure in the background.
This is a video I shot at the Natural Bridge Zoo. This is a temp setup for the Young Dromedaries. I haven't seen other zoos around do this temp displays. Not sure if this is common or not.
