The scales on the trunk and tail of a perch are arranged in overlapping rows that run diagonally along the body. These scales are known as cycloid scales, which are round or oval-shaped with smooth edges. The scales on the trunk are larger and more prominent compared to those on the tail, providing protection and flexibility for the fish as it moves through the water.
