Otolith- This is also called the “ear stone”. It rests on top of a bed of sensory hair cells and because of the
downward pull of gravity it is able to provide the fish with information about its vertical orientation in
the water. A typical fish has three different ones called the lapilli, asterisci, and sagittae. Many scientists
will use these to determine how old a fish is as well.
