 regions, and there was no hope of passing the shark. 

 Under water, especially after being submerged for nearly 

 a minute, there is no time for planning, and the diver 

 gave himself up for lost. 



Suddenly, the Sepia's ink-bag flashed across his mind. 

 He dived down again, stirred up the sand with his hands

 the shore before the shark could find him. 



Even in the fossil Sepise the ink-bag has bee,n pre-

 with its own ink.

 mostly feeds in the dark, could almost do without eyes ;
