the main difference between these and arabian (dromedary) camels is the number of humps each has. bactrians have two instead of one. consequently, they can go even longer without plants and water in even harsher conditions (from about 40°C to -30°C) with the extra storage. i suppose it is fitting that when they can drink water, they can do so at ridiculously fast rates. like more than two gallons per minute fast. bactrians are the only true wild camels in the gobi dessert and yet they are very endangered. estimates say there are less than 1000 left. camelus bactrianus in moleskine.
