Description
Summary:Diet of the marine cladoceran Podon intermedius from Port Phillip Bay, Australia, was studied using feeding experiments and scanning electron microscopic examination of faecal pellets. The most common prey items identified in faecal pellets were large diatoms, mainly Rhizosolenia sp. This genus was also the dominant diatom in the environment at the time of sampling. Animal remains were not found in the faecal pellets. Phytoplankton of various sizes were offered to P. intermedius in feeding experiments, but significant feeding only occurred on Rhizosolenia. P. intermedius is apparently a raptorially-feeding herbivore.
