Although only a head is hard although big feather and the body are soft, and it is short, it has a strong large jaw. If the body is caught by hand carelessly, a jaw will be bent and it will bite. Since the power of a large jaw is strong, the skin will be bit off simply. It is just a snake dragonfly. Since an abdomen is very soft, it will be shrunk a mere shadow of its self with drying.
