annual rings
A clams growth rings can be, tan, gold, brown, even red.
A shell with a thin ring indicates that it grew slowly, indicating poor environmental conditions.
Palms do not show growth rings.
The rings on a clam show where the growth of one year ends. Basically you can count the rings to see how old the clam is just like a tree! Each ring shows the growth of that year.
Tree growth rings (and some other kinds like those of shells) are caused by the difference in growth during the different seasons: autumn and winter less growth, spring & summer more growth.
the size of the rings would depend on the growth cycle of the tree. If the growth time for a certain year is longer, the ring will be wider, it the growth time of the year is shorter then the ring will be smaller.
Yes, the scales do overlap. The overlapping makes a more complete covering than if the scales butted up to each other. When the fish bends, the overlapped scales have freedom of movement, yet still keep the covering of the body intact.
