extremely sensitive to depth pressures. It is 

 through the aid of this organ, and not by means of 

 the organs of sight, that they are enabled to deter- 

 mine their nearness to the surface. That the squid 

 is without such an organ or its equivalent, is cer- 

 tain; thus, not being aware that it is so close to 

 the top, in its blind rush it propels itself clear of 

 the water — oftentimes to precipitate itself in 

 enormous numbers upon the sandy shores and 

 rocks.
