Introduction to Dinoflagellates -Dinoflagellates are unicellular protists which exhibit a great diversity of form. The largest, Noctiluca , may be as large as 2 mm in diameter! Though not large by human standards, these creatures often have a big impact on the environment around them. Many are photosynthetic, manufacturing their own food using the energy from sunlight, and providing a food source for other organisms.

Mote Marine Laboraory Red Tide Pages -Red tides occur throughout the world, drastically affecting Scandinavian and Japanese fisheries, Caribbean and South Pacific reef fishes, and shell fishing along U.S. coasts.
