What is the thing that hangs down off of a moose's neck?
I'm in science class, and I need to know!
The part is known as a dewlap. It is a piece of skin that hangs down from the neck. The purpose of this part is said to be for spreading the scent during mating rituals. You can go to http://en.wikipedia.org/wiki/Dewlap for more reference.
It's called a bell.
