Gametic meiosis occurs in Noctiluca. If they are hungry, dinoflagellates aren’t to be messed with! While they prefer to chow down on other small, single-celled organisms, dinoflagellates aren’t afraid of grouping together in large numbers to tackle larger prey. When they do this, they insert their feeding … dinoflagellates which spread over 6 orders of magnitude with an average of 242 mM (n=61) and include the widest and highest DMSP concentrations reported in Reproduction..54 1.3.7.

Paramecia division.

Nutrition among dinoflagellates is autotrophic, heterotrophic, or mixed; some species are parasitic or commensal. About one-half of the species are photosynthetic; even among those, however, many are also predatory. Although sexual processes have been demonstrated in a few genera, reproduction is largely by binary or multiple fission. Under favourable conditions, dinoflagellate populations may reach 60 million organisms per litre of water.
