Do they always have their mouths open making that horrible sound that they make? Every picture I see of a camel looks like this, Tang Dynasty (8-9th century AD) clay figures of camels show them this way, too. I guess calling camels domesticated is somewhat wishful thinking on our part, isn't it? :-)

they do hve their mouths closed most times when they r not chewing.. but i just love the moment of evil laughter
