cycloid scales have the same number of scales their entire lives - the scales enlarge to accommodate a fish’s growth (scales that are lost to injury will be regrown). This results in a pattern of concentric growth rings on the scale, which look similar to the growth rings in the trunk of a tree. The growth rings on a scale are known by scientists as circuli (singular circulus). As cycloid and ctenoid scales increase in size, growth rings called circuli become visible.
