Dromedary Camel have one hump, Bactrian Camels in Asia have two humps on their back.
Dromedary Camel have been completely domesticated centuries ago so there technically no "wild" ones left.
Today, they are almost all entirely owned by someone but some have become feral again.
They wander some of their native range so I'll liberally count this as wildlife.
