Blue Whales 



in the case of Blue whales, and as the number is so small they are shown individually 

 in the following table : 



Those marked with an asterisk are South African whales. There are few enough 

 data here for any comparisons to be made, but it can be said that there is no indication 

 of any difference in the width of the baleen between either males and females or South 

 Georgian and South African whales. 



Measurements of the spacing of the largest baleen plates similarly give only negative 

 results. The distance separating these plates varies from about i-ocm. in i6-om. 

 whales to about 2-5 cm. in 27-0 m. whales. The readings are plotted in Fig. 50 from 

 which it will be seen that no particular distinction exists between males and females 

 or between whales of South Georgia and South Africa.
