 Blue Shark. Fenn, Brit, Zool, 



Of a more slender and elegant shape than most 

 others of the genus : colour above deep glaucous or 

 blue-green, beneath white : head rather large, 

 with the snout very long and pointed, and the 

 mouth wide, and placed very far beneath : teeth 

 nearly triangular, lengthened, sharp-pointed, and 

 disposed in three or four rows : eyes large : first 

 dorsal fm seated about the middle of the back, the 

 second very near the tail, opposite the anal fin : 

 tail of moderate size, deeply bilobate, with the 

 lower lobe much larger and longer than the upper. 

 This species, which is the most beautiful of all the 

 Sharks, in point of colour, grows to the length of 

 ten, twelve, or even fourteen feet, and is an in- 

 habitant of almost all parts of the globe. It is 

 a very voracious and bold fish, and scarcely less 

 dreaded by sailors than the common or white 

 Shark. It is said principally to prey on herrings, 

 shads, and tunnies ; it frequents several of the 

 British coasts, particularly those of Cornwall, during 

 the pilchard-season, and is at that time taken with 

 large iron hooks prepared for the purpose.
