The Cuttle-fish is common along the shores of the 

 Mediterranean, where large numbers are captured for 



food, for their ink, which 

 is made into the pigment 

 sepia (se'pl a), and for their 

 supporting, calcareous

 Squids, some of which

 while its threatening look so alarmed him that he loudly called for assistance. 

 His release was at last effected only by killing the cuttle-fish with the boat-hook, 

 and cutting off its arms bit by bit.
