Crustacea represented 90% and 84% of the total numbers of prey recorded for B. antilliensis and B. globulifera, respectively. Other prey types included polychaetes, mollusks. and urochordates.

Both species ingested signifi- cantly more prey items at night than during the day (Mann-Whitney t/test; < p ); during the day, however, B. globulifera ingested significantly more prey than B. antilliensis (Mann-Whitney L'test; <p< ).
