It is hard to say for sure. I have raised several genra of fish from fry, so
could monitor their feeding habits on other fish. It seemed most knew
instinctivly to go for the head of something running from them, or hit mid
section and turn the fish head first. What is more amazing is fish that
often strike the center of the body. They are so quick to know which end is
the head and work the prey around for the swallow.
Though , the older the fish got, the better they were at hitting their mark.
