Fish Sides

How Can You Determine the Age Of a Fish?
One way is by the scales, which can have growth rings like trees! The part of the scale inside the skin contains clusters of ridges called "annuli." Each cluster equals one year's worth of growth.

It is as easy as it seems: dorsal means top, ventral means bottom, posterior means rear, and anterior means front.
