Figure 139. — The highly distinctive pattern oJ the Atlantic white-sided 

 dolphins is clearly visible in this animal stranded in Scotland. Even if the 

 color pattern has faded, however, this species should be easy to identify. 

 The 30-40 teeth in each of the upper and lower jaws permit distinction 

 from the white-beaked dolphins, which have only about 22-28 per side in 

 each jaw. {Photos by B. ThtUock, courtesy of A. S. Clarke.)
