All fish have ears, just not the standard form we're accustomed to. By that I mean that instead of having an ear that protrudes from the side of their head fish instead a fish's ear is in its inner skull. Stripers actualy have an accute sense of hearing with an auditory range greater than our own. And as for the lateral line, a bass uses its lateral line and hearing together in order to locate a wounded fish, remember, all a sound is is the vibration of air/water molecules.
In short:
Loud rattle=fish
