The different species of fecal bacteria isolated from marine animals were fed to Tigriopus, Calanus, Paracalanus, Oncaea, Acartia, Candacia, Euchaeta, Euphausia and Macurura. The experimental results of fecal pellets production revealed that the bacteria could be ingested as a form of small micelle or large floc, depending on the developmental degree of the filtering mechanism of animals. Also, the nutritive food value of bacteria or its flocs for the zooplankton was ascertained by surviving longevity, growth, and reproduction. It could be emphasized that as the enormous amounts of fecal bacteria are considered to be voided by marine animals, the bacterial flocs formed by such types of fecal bacteria have an important role as direct food for zooplankton and not only as a decomposer in the sea. So, marine animals beyond the limit of phylums, play a role of producer as well as consumer through the fecal bacteria.
