Heterotrophic zooplankton is commonly much more diverse than phytoplankton. Representatives of most animal phyla either belong to the plankton throughout their life or have certain developmental phases in the plankton - hence they are called holo- or meroplankton, respectively. Meroplanktonic larvae do not resemble their parents, but transform into the adult form by metamorphosis (indirect development). Whereas rotifers are very abundant and diverse in freshwater plankton, there are only a few species in the marine plankton. Most of the rotifers are very small (<1 mm) and consist of about 1000 cells (eutely). The body is surrounded by a proteinaceous shell (lorica) made of keratin that shows spiniform emarginations. A charasteristic feature is the corona at the anterior part of the body. The beat of its cilia serve for locomotion and feeding. From the DVD: DAHMS, HANS-UWE (Hongkong); FIEGE, DIETER (Frankfurt a.
