Figure 1.— Aerial view of two right whales feeding in a slick of collected plankton 

 in Cape Cod Bay, Mass., 1 May 1979 (same individuals shown in Fig. 2). Note the 

 pattern of head callosities and the pale appearance of the baleen underwater.

FIGURE 2.— View of two right whales seen from a boat in Cape Cod Bay, Mass., 2 May 1979 (same individuals as in Fig. 1). Note the 

 limitation in visibility through the water surface, yet more visibility in details of head calosity patterns. These whales were observed 

 for nearly 5 h as they fed nearby at the surface, but we found it difficult to record the complete callosity shape from these surface 

 views. Photo by K. E. Moore.
