camels and salt

Per this page: How to Buy a Camel, camels need to eat 5oz (140g) of salt per day.

Wow, that is a lot. This paper confirms it: How much, how often and in which form should salt (NaCl) be given to a camel?

The first page suggests providing them with a salt block, but the paper advises against it, as they can't lick well and chewing on the block can hurt their teeth.

Lest anyone think I want to buy a camel, I came across that first link here. I was also curious about the statement "keep them [the camels] away from horses", and posted a comment there on that.

In some photos of camels, it looked to me like a long tongue hanging out of their mouth. But another page I read said they have small tongues. The thing that I thought was a tongue is a "dulla":
The male dromedary camel has an organ called a dulla in its throat, a large, inflatable sac he extrudes from his mouth when in rut to assert dominance and attract females.

Camels and some other animals have a Vomeronasal (aka Jacobson's) organ above the hard palate in their mouth.

Flehmen response : that thing cats and other animals do, where they scrunch up their face and inhale when they smell certain things... this is done to get the smell into that vomeronasal organ.

Lest

Lest is a neat word. I know what it means, but had difficulty in trying to verbally define it or explain it.

Dictionary definitions:
"for fear that; so that (one) should not (used negatively to introduce a clause expressive of an action or occurrence requiring caution)"

"so as to prevent any possibility that"

"with the intention of preventing (something undesirable); to avoid the risk of"

That's quite an impressive conveyance of meaning for such a small 4-letter word.

Etymology: from "whereby less that"
