Crangon franciscorum and Palaemon macrodactylus are carnivorous shrimp in the Sacromento-San Joaquin River Delta. These shrimp prey primarily on the opossum shrimp, Neomysis mercedis. Behavioral and morphological differences result in P. macrodactylus stomachs containing a greater number of prey, on the average, than C. franciscorum. Dietary overlap and similarity were high (>80%) throughout the study. C. franciscorum is generally larger than P. macrodactylus and is able to ingest larger prey… Expand
