In some localities it is scarcely possible to catch fishes with 

 the hook and line, as the fish hooked is immediately attacked 

 by the " Caribe " (as these fishes are called), and torn to 

 pieces before it can be withdrawn from the water. The 

 Caribes themselves are rarely hooked, as they snap the hook 

 or cut the line. The smell of blood is said to attract at once 

 thousands of these fishes to a spot. They are most abundant 

 in the Brazils and Guyanas ; some forty species are known, 

 and referred to the genera Mylcsinus, Scrrasalmo, Myletes, and 

 Catoprion.
