Abstract
During the feeding process of the grasping and chewing amphipod Calliopius laeviusculus, a significant portion of the prey body contents is lost to the surrounding water. The amount of material lost decreases as the size of the predator increases. If this loss is ignored in ingestion studies, the result is a substantial overestimation of assimilation and assimilation efficiency, as determined by the gravimetric method.
