Figure 50. — Right whales frequently throw their tail flukes high into the 

 air and then slip nearly vertically beneath the surface. Note that the rear 

 margin of the flukes of this species, unlike that of the humpback whale, is 

 smooth, broad, and concaved distinctly towards a deep fluke 

 notch. {Photos from the northern North Atlantic by K. C. Balcomb [a-g]
