HIROTA: NATURAL HISTORY OF PLEUROBRACHIA BACHEI IN LA JOLLA BIGHT 



Table 7. — Stomach contents over the period 8 March 1970 to 2 June 1971 for 10 size classes of postlarval Pleurobrachia bachei. Data 

 are the percentage by numbers (upper value) and by carbon mass (lower value) of each prey category in the stomachs for each size class 

 of ctenophore calculated separately. The first 10 prey categories are given in ascending order of body mass; thereafter the order is by 

 taxonomic group (e.g., copepods, cladocerans, crustaceans, chaetognaths, etc.). The numbers indicated in parentheses below each size 

 class are the number of ctenophore stomachs examined per size class. Total numbers and total carbon refer to values of all prey in each 

 ctenophore size class. Carbon mass is not calculated for protozoans.
