Why Not Save the Marine Mammals of the Pacific?* 



By Barton Warren Evermann. 

 Director, Museum California Academy 

 of Sciences 



The biggest animals in the world are 

 found in the Pacific ; and that seems as 

 it should be and entirely proper, for is 

 not the Pacific the biggest ocean in the 

 world? Just how many kinds of whales 

 and other marine mammals there are in 

 the Pacific we really do not know ; and 

 that is highly improper, not to say dis- 

 graceful, for we surely ought to know. 



The animals I refer to are the fur 

 seals, sea lions, porpoises, elephant seals, 

 walruses, whales and the like. Recently 

 I examined all the available literature 

 at hand and was able to make up a list 

 of the species of marine mammals of 

 the North Pacific. The list contains 9 

 baleen whales, 5 sperm whales, 12 por- 

 poises, killers and dolphins, or a total 

 of 26 cetaceans ; and 1 bear, 2 sea ot- 

 ters, 4 fur seals, 10 sea lions and har- 

 bor seals, and 1 walrus, or a total of 18 

 carnivores ; or 44 in all. 



The following is a list of the species 

 that we may recognize for present pur- 

 poses :
