 and striped bass), or for purposes of feeding, as the robalo, 

 corvina, and other shore-fishes of the tropics. Some live 

 among rocks alone, some in sea-weed, some on sandy shores, 

 some in the surf, and some only in sheltered lagoons. In 

 all seas there are fishes and other marine animals, and 

 each creature haunts the places for which it is fitted.
