Fig. 99. — Scallops over one year old, as shown by the formation of the annual 

 growth line, which is caused by cessation of growth during the winter months. 

 Any scallop which does not possess this annual growth line is less than one year 

 old, and is a "seed" scallop. The present legal definition of a "seed" scallop is 

 based on the annual growth line, as its absence indicates that the animal has not 

 as yet reached its spawning season, and is, therefore, an immature animal.
