Abstract
The concentric bands or rings which are
evident in transverse sections of echinoid spines
have attracted the interest of biologists for more
than a hundred years. First, the basic cause of
ring formation remains obscure although at
least two controversial hypotheses have been
proposed, and elucidation of the ring-forming
mechanism is important to a better understanding
of the general processes involved in growth.
Second, there is a practical aspect to the "growthring
problem" because, if the number of rings
in a spine is closely and directly related to the
age of the animal, killing the urchin for age
determination is obviated, thus facilitating ecological,
population, and other practical studies
in marine research.
