A camel is an even-toed ungulate with distinctive fatty deposits, or humps, on its back. It is very similar to the real world camel. Camels are used as transport in Essos. There has been no mention of camels in Westeros. Camels are popular transport in Qarth. A camel cavalry, or camelry, is also used in combat by the Qartheen.
A Clash of Kings
When Jhogo returns to Daenerys Targaryen and her khalasar in Vaes Tolorro, he brings Pyat Pree, Xaro Xhoan Daxos and Quaithe. The three strangers are all riding camels, creatures Daenerys does not recognise.
A column of camelry emerge from Qarth as Daenerys Targaryen's honour guards upon her arrival outside of the city. The Qartheen camelry riders wear scaled copper armour and snouted helms with copper tusks and long black silk plumes. They sit high on saddles inlaid with rubies and garnets. Their camels are dressed in blankets of a hundred different hues.
In Qarth Daenerys soon discoveres that horses cannot abide the close presence of camels. As she rides her silver down a great arcade her mare shies when Xaro Xhoan Daxos and his camel approach her.
