Mung beans

Are mung beans what we know as bean sprouts? I can't say I've ever seen the dried beans let alone the plant, and that's after years in the Far East. My excuse is I was more interested in eating than growing in those days.

I reckon they'd be bushy plants and the beans quite thin and short and in bunches. If I'm correct about the beansprouts, I wonder why that sort of bean is chosen for sprouting rather than others.
