Figure 34. — Head views of surfacing humpback whales. Note the rather broad 

 rounded appearance of the top of the head and the small head ridge, which extends 

 from just in front of the blowholes to near the tip of the snout. In humpback whales 

 the single central head ridge characteristic of most balaenopterid species is replaced 

 in prominence by a series of knobs, some of which are oriented along the same line as 

 the head ridge. On the animal in the inset photo note also the characteristic rounded 

 projection below the tip of the lower jaw, heavily encrusted with barnacles. (PAotOt

Figure 35. — A mother humpback whale with her newborn calf off the northern West Indies. Newborn humpback whales are from 12 to 15 feet (3.7 to 4.6 ml 

 long and are colored like the adults. Note the mother's long white pectoral flipper, clearly visible below the surface. {Photo by H. E. Winn. )
