Feeding, growth and respiration in the polychaetes Nereis diversicolor (facultative filter-feeder) and N. virens (omnivorous) - a comparative study. Filter feeding, found in the mysticete whales and three species of pinnipeds (crabeater seals, Lobodon carci- nophaga ; leopard seals, Hydrurga leptonyx ; and Antarctic fur seals, Arctocephalus gazella) is the most unique of these adaptations for feeding, and is not found in any terrestrial mammals. Filter-feeding in the polychaete Nereis diversicolor: A review. It has been discovered that the facultative filter-feederN. diversicolor may meet its metabolic requirements on a pure diet of phytoplankton, just as a typical obligate filter-feeder. Consequently, this worm is likely to be a hitherto undervalued key organism in the control of phytoplankton production in many shallow brackish water areas.

Filter feeding, found in the mysticete whales and three species of pinnipeds (crabeater seals, Lobodon carci- nophaga ; leopard seals, Hydrurga leptonyx ; and Antarctic fur seals, Arctocephalus gazella) is the most unique of these adaptations for feeding, and is not found in any terrestrial mammals. Abstract. Nereis diversicolor O. F. Müller (Annelida: Polychæta) has been recorded as feeding on small crabs, mussels, pieces of algæ, and also on detritus, and stress has always been laid on the role of the powerful jaws in seizing prey and dragging it down into the burrow 2. The discovery of a filter-feeding mechanism is therefore of interest. Filter-feeding in the polychaete Nereis diversicolor: A review. It has been discovered that the facultative filter-feederN. diversicolor may meet its metabolic requirements on a pure diet of phytoplankton, just as a typical obligate filter-feeder.

Field studies in Danish waters (Odense Fjord and Fyns Hoved) showed that the facultatively filter-feeding polychaete Nereis diversicolor, kept in U-shaped glass tubes elevated 15 cm above the bottom, is able to grow on phytoplankton as the sole food source.
