Dinoflagellates are photosynthetic, they are the great producers of the ocean, phytoplankton. TThier chromosomes lack histones and they have two flagella of unequal lenghts. Some dinoflagellates are bioluminescent and some produce a pigment so that a proliferation of dinoflagellates may cause a 'red tide.' Humans do not directly consume dinoflagellates, but humans consume shellfish that consume dinoflagellates. Shellfish may concentrate certain neurotoxins produced by dinoflagellates and cause neurlogical symptoms in humans who consume those shellfish. Examples of dinoflagellates are Gymnodinium and Gonyaulax.

13. The toxins produced by dinoflagellates are heat stabile, so cooking does not prevent the possibility of shellfish poisoning. Make two recommendations to prevent consumption of dinoflagellate neurotoxins based on what you know, or pose two questions about what you would like to know. Amoebozoa have lobe like pseudopods for motility. Slime molds are classified in this group and will not be covered on any exam. Two examples are Naegleria and Entamoeba, pathogens.
