268 THE LIVING ANIMALS OF THE WORLD 



SHARK (of which a photograph, taken at Mevagissey, is given below), illustrates in its harmless 

 person the fallacy of condemning nil sharks as man-eaters, since in this, the largest of its 

 race, we have an absolutely innocuous fish. From its habit of lying at the surface with the 

 large back-fin erect, it is also known as the Sail-fish, while the equally appropriate name of 

 Sun-fish sometimes causes confusion with other British fishes properly so called. 



A commoner British shark is the BLUE SHARK, small examples of which, weighing 30 

 or 40 Ibs., the writer has often killed with the rod at Mevagissey. When thus hooked, this 

 fish has a curious and very trying habit of revolving rapidly in the water, scoring its own 

 granulated skin with the line. The PORBEAC.I.K-SHARK, another Cornish species, is of thicker 

 build than the last, and swims with far less graceful movements. It is a deep brown colour 

 above, and its general outline may be likened to that of a torpedo. The I'"OX-SHAI\K, or

 is easily recognised, even at considerable distances, by the disproportionately long upper 1 

 of the tail-fin. This is the shark which attacks certain of the Whale Tribe. Many who 

 stay at home find it agreeable to cast doubt on the ^tory ; but the writer has, in Australian 

 seas, witnessed the sight of two of these sharks flinging themselves on the back of an 

 apparently exhausted whale in such unmistakable circumstances that the only alternative 

 (which the reader may accept, if preferred) is to suppose that they were all congenial 

 playmates.
