TYachinotus carolinus and Mugil curema) may actively 

 seek them as havens which are relatively free of 

 predators. Species inhabiting tidal pools are subjected to 

 sudden fluctuations in temperature and salinity.

We are grateful to Thomas D. Bryce, Michael N. 

 Cohen, Bruce A. Daniels, Charles H. Farmer, Donna 

 Kim Harper, J. S. Hopkins, Mark B. Maddox, James F. 

 McKinney, William A. Roumillat, and Barry Stamey for 

 assistance in the field. Thomas D. Bryce, Charles H. 

 Farmer, and James F. McKinney aided in numerous 

 ways in processing some of the collections. Robert L. 

 Shipp (University of South Alabama) identified the 

 specimen of Sphoeroides spengleri. James F. McKinney 

 and William A. Roumillat coded and checked data for 

 the analyses by computer. B. M. Martin of the Depart- 

 ment of Radiology, Medical University of South 

 Carolina, made the radiographs used in this study. R. C. 

 Duncan, C. B. Loadholt, and M. C. Miller, m, of the 

 Department of Biometry, Medical University of South 

 Carolina, provided assistance on statistical methods and 

 access to computer facilities. This study was supported 

 in part by a traineeship grant to James K. Dias from the 

 Department of Health, Education and Welfare, Public 

 Health Service, National Institutes of Health. Dale R. 

 Calder (South Carolina Wildlife and Marine Resources 

 Department, SCWMRD) verified the nomenclature used 

 for invertebrates. Alice E. Charest, Karen R. Swanson, 

 and Peter B. Laurie (all of SCWMRD) assisted with the 

 manuscript preparation. Charles A. Barans 

 (SCWMRD), Peter J. Eldridge (SCWMRD), C. B. 

 Loadholt, John J. Manzi (SCWMRD), and John W. 

 Tucker, Jr. (North Carolina State University) reviewed 

 the manuscript.
