This is the second most important reason fish strike, particularly why bass strike, and it accounts for 20 to 25 percent of the bass I catch in a year's time. A bass's reflex action is like the behavior of any predator. Kind of like a cat pouncing on a mouse.
A lurking bass is seeking  concealment to hide or camouflage his body from the wary eyes of small baitfish of some description. So the bass is in the shadows of an object, in this case an ambush point.
