Feeding by Euplotes mutabilis (Ciliophora, Hypotrichida)
Experiments on the capture and ingestion of microspheres and algal cells of different sizes presented at different concentrations, alone or in combination, showed that feeding activity and ingestion rates were dependent on the concentration and size of food particles; larger particles were preferred to smaller ones and algal cells to microspheres of similar sizes, at the same concentration. The membranelles of Euplotes create water currents carrying suspended particles, filter particles from the current and direct them to the cytostome. Specialised frontal membranelles may play some part in recognition of prey, but the principal selection site is probably the membrane lining the forming food vacuole at the cytostome.

Abstract
Experiments on the capture and ingestion of microspheres and algal cells of different sizes presented at different concentrations, alone or in combination, showed that feeding activity and ingestion rates were dependent on the concentration and size of food particles; larger particles were preferred to smaller ones and algal cells to microspheres of similar sizes, at the same concentration. The membranelles of Euplotes create water currents carrying suspended particles, filter particles from the current and direct them to the cytostome. Specialised frontal membranelles may play some part in recognition of prey, but the principal selection site is probably the membrane lining the forming food vacuole at the cytostome.
