BOTTON and ROPES: POPULATIONS OF HORSESHOE CRABS 



progress which will evaluate the importance of 

 horseshoe crab predation to these bivalves. 



ACKNOWLEDGMENTS 



We are indebted to the scores of individuals 

 who enumerated and weighed horseshoe crabs at 

 sea. Special thanks are given to Ambrose Jearld 

 for encouraging this study and to Linda Patanjo, 

 Eva Monteiro, Ralph Mayo, and Loretta O'Brien 

 for making data logs accessible and comprehend- 

 able. Steve Murawski, Joe Idoine, and Gary Shep- 

 herd assisted with computer analysis. Brian 

 Kelly (Commonwealth of Massachusetts, Divi- 

 sion of Marine Fisheries) and Richard Sisson 

 (Rhode Island Department of Environmental 

 Management, Division of Fish and Wildlife) have 

 kindly collected and allowed us to use data on the 

 occurrence of horseshoe crabs in their trawl sur- 

 veys. David Bunting provided us with the deep- 

 water photograph obtained on RV Eastward 

 cruise E-9-66. The manuscript was improved by 

 the critical reviews of Steve Murawski, Mike Fog- 

 arty, Steve Clark, and Carl Shuster. The senior 

 author is grateful for the support provided by the 

 Fordham University Research Council Biomedi- 

 cal Support Program, and the National Marine 

 Fisheries Service.
