The Méhari is a particular race of dromadaire. The Méhari is considered the most nobble dromadaire and is widely used in Sahara by nomads. This dromadaire comes from Algeria.
Le dromadaire n'a qu'une seule bosse. Le chameau a deux bosses.
How would you say "une bosse" for a camel? A bump?
(Méhari is also the name of a French car that was manufactured by Citröen.)
Hope this helps.
