These variations of growth put their stamp on the fish, the shape of which depends on its growth-history. And in waters, like those off the Norwegian coast, subject to great variation and extending south and north through so many degrees of latitude, an infinite variety in growth-types appear as a natural consequence. Some of these types may perhaps, through generations, be subjected to the accumulating influence of surroundings, thus possibly giving rise to races. Other and minor variations in growth may perhaps be considered as.
