What else does a bearded dragon do if it feels threatened?

If a bearded dragon feels threatened, it may display several defensive behaviors, such as puffing up its body, flattening out against the ground, or inflating its beard to appear larger. It might also change its color to a darker shade to blend in with its surroundings or prepare to flee by running away quickly. In extreme cases, it may open its mouth and hiss as a warning to potential threats.
