In the repeat episode from Series B shown on Dave last night, Alan said something about camels storing water in their humps.

THAT IS COMPLETE RUBBISH!!

Camels do not store water in their humps, which consist, rather, of fatty tissues acting as food reserves. In fact, a camel doesn’t store water anywhere in its body. It survives arid conditions by being able to drink a huge amount of water in one sitting (something like six litres) and then go a long time without drinking again. It can also tolerate considerable fluctuations in its body temperature.

It amazes me that Stephen didn’t take points off Alan for that piece of urban myth about camels!

Would that have been Series 2, episode 1? Possibly this bit:

Nope.

Forgive my ignorance, but drinking a lot of water at once and not having to do so again for a long time sounds rather a lot like storing water somewhere. Not necessarily in a hump of course, but presumably it's still there.

Wiki wrote:
Their ability to withstand long periods without water is due to a series of physiological adaptations. Their red blood cells have an oval shape, unlike those of other mammals, which are circular. This is to facilitate their flow in a dehydrated state. These cells are also more stable[7] in order to withstand high osmotic variation without rupturing when drinking large amounts of water (100 litres (22 imp gal; 26 US gal) to 150 litres (33 imp gal; 40 US gal) in one drink).[8] Oval red corpuscles are not found in any other mammal, but are present in reptiles, birds, and fish.[9]

So it sounds like they store the water in the blood. It's also delayed through the stomach to help, and might be stored subcutaneously too.

There's lots more good stuff about water preservation on the wiki too.

How many points should we take off you do you think Susannah?

In Series C, Dara Ó Briain had points taken off for something he had done in Series B – which was merely saying something only marginally inaccurate about the triple point of water. Now, what was that compared with the unpardonable crime of believing that camels store water in their humps? I am going to send a PM to Flash about this and press for points to be taken off Alan in a future series for this outrageous urban myth about camels!

But if they store water in their blood, and their hump contains blood (not static of course), then it would seem to me that technically water is stored in their blood. Sheer pedantry of course, but isn't that rather what QI is made of?

What a brilliant tautology! I love it!

Anyway, Flash has replied to my PM, saying he agrees with me. There you are, folks. Watch out for a forfeit for Alan on this question in a future series!

I suspect that if I were walking through the desert that I could drink close to 6 litres in one go, and I'm pretty sure camels can drink a whole lot more than that.

"A camel is a horse designed by committee"
- so the saying goes.

Considering the clever design of camels; is this a eulogy for committees?

I thought it was elephants were mice designed by a committee.

Surprised Reddy hasn't mentioned these:



They're advertised as "Extra sour, liquid filled", mmmm....

In addition to the Dromedary camel of Africa and Asia and the Bactrian camel of Asia, the Camelid family includes four more relatives in South America. The Llama is best known along with the Alpaca, Guanaco and Vicuna. None of these four have humps (for storing water or blood or fat) but do share many other camel features.

What I found really interesting was that they have sex lying down. I'm not sure that it's face-to-face, but there it is.

cf Politicians

They are always lying
They have sex (unconfirmed)
They have two faces and therefore have no need or a partner
They frequently get the hump

Llama blood has some unusual properties and under a microscope the red cells look oval. It is also being developed for anti-terrorist use.

Rotten terrorist! A lot of Llamas are going to lose a lot of blood over this!
