Perryman and Lynn: Stock and school structure of Stenella coeruleoalba 



131 



Acknowledgments 



A. E. Dizon, D. P. DeMaster, W. F. Perrin, and two 

 anonymous reviewers read the manuscript and pro- 

 vided very useful suggestions. Valuable assistance 

 and specimen data were provided by S. Chivers. Sev- 

 eral of the photographs for this analysis were taken 

 by J. Gilpatrick and R. Westlake. This work would 

 have not been possible without the field support of 

 the Officers and Crew of the NOAA Ship David 

 Starr Jordan and the pilots and mechanics of 

 NOAA's Aircraft Operations Center.
