The Killer Whale (Orca gladiator) is ubiquitous in its distribution, but is 

 particularly abundant in the Antarctic seas. Hunting in herds generally of a 

 dozen or twenty, but sometimes of nearly a hundred together, it is seen 

 commonly along the edge of the floes as the ice breaks up, evidently on the 

 look out for Seals and Penguins. 



Its high dorsal "fin," and the yellow saddle-mark on its back, suffice to 

 distinguish it from all other Cetaceans.
