THE HUMPBACK WHALE 



49 



INTERNAL 



Intestinal parasites were only found in one Humpback whale of the series. This was 

 a male examined at Durban which had a few nematode worms, immature specimens of 

 an Anisakis sp., in the stomach (Baylis, 1929). 



On the other hand the kidneys of this whale are frequently infested with nematode 

 worms. They occurred in both sexes and were found in twenty-three out of thirty-five 

 whales examined for them. In addition they were also present in the urethra and penis 

 of four male Humpbacks. The species is probably a Crassicmida {} boopis). 



No other internal parasites were found in the Humpback whales at South Georgia or 

 South Africa.
