This book describes larvae of bivalves and echinoderms, living in the Sea 

 of Japan, which are or may be economically important, and where adult forms 

 are dominant in benthic communities. Descriptions of 18 species of bivalves 

 and 10 species of echinoderms are given, and keys are provided for the iden- 

 tification of planktotrophic larvae of bivalves and echinoderms to the family 

 level. Information on identified species is preceded by a description of the 

 morphology, physiology, and behavior of larvae of the given classes. 



The book is addressed to marine biologists, embryologists, zoologists, and 

 specialists engaged in fisheries.
