There are two species of camel, Dromedary (Arabian) with one hump and Bactrian with two humps.

Mnemonic for this is to place the initial letter of each on its side -

B(actrian) has two humps and D(romedary) one.

That's clever - I haven't heard that before.

Here's an interesting overhead view of Camels in the desert. Look closely, the camels are the little white lines in the picture. The black you see is just the shadows!

That is just such a beautiful image., and so deceiving. Great.
And the info was quite informative too. lol

What do camels store in their humps?
What species of camel live in Mali?

In their humps, don't they store a supply of fat for errm...some reason? Not water :P.

I read somewhere that the only country in which camels live in the wild is Australia.

Camels store fat in their humps. However, it is similar to storring water because when they metabolise the fat water is a product from the reaction. The purpose of the hump is to provide a supply of water, even if the hump does not store water itself.

Quite a few American homesteaders are turning to raising camels. People think that they are grumpy beasties but reared with love and affection they make surprisingly gentle and faithful pets - if you can put up with a pet which weighs over a ton.

They store fat in their humps. The reason for this is that for every kilogram of fat stored, they are able to metabolise around 1.4kg of water, so it's a more efficient method of storing water.

The fat that they store is made up of triglycerides, each of which consist of a glycerol head and usually three stearic acid tails, though I believe other fatty acids are also used.

Can this be true? I looked at it and thought that 1.4 kg can't come from 1 kg. Then I thought about the Oxygen but then I thought about the Carbon Dioxide and whether than balances out the Oxygen. Normal formula for respiration is (if my creaking mind remembers correcty)

C6H1206 + 6 O2 = 6 H20 + 6 C02

So 1 mole of sugar (6 x 12 + 12 x 1 + 6 x 16) = 180 grammes carried

Add that to 6 moles Oxygen (12 x 16) = 192 grammes extracted from the air

Produces 6 moles water (12 x 1 + 6 x 16) = 108 grammes water

and 6 moles CO2 (6 x 12 + 12 x 16) = 264 grammes Carbon Dioxide

Scaling up 1 Kg of sugars metabolises into 0.6 Kg of water.

If this is true about fat being a more efficeint way of storing water than water, then what is it about fat that makes this so? I would guess a higher ratio of Hydrogen to Oxygen such that more of the water formed comes from atmospheric Oxygen.

My guess is that there are 2 additional sources of water here:

1. The fatty triglycerides perhaps release water when they are converted into sugar for respiration?

2. The glycerol component of the triglycerides are (hoping I'm using the correct word) hydrophilic and therefore the fat will be stored in vesicles in the cell that are floating in the normal cytoplasm in the cell. Perhaps the solution that the vesicles are in can also be a source of water (of course this would actually be stored water so I'm highly suspect that this suggestion is false. Go back to my first one).

Is this why so many diets appear to work so well for the first week, but it's always called 'water loss'? The fat stores are giving up their water rather than being depleted?

Camel happens to be the name of my favourite band of all time.
