The first shot is a ventral view showing the multiple-hinged, extendable lower jaw (similar to that seen in dragonfly nymphs). Here it is in the "closed" position but it is thrust out quickly to grasp prey that might otherwise seem out of reach.
The second, lower magnification shot, is a view from above showing the trachea tubes branching through the body.
