Some species are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are colorless predators on other protozoa, and a few forms are parasitic (see for example Oodinium, Pfiesteria).Some dinoflagellates produce resting stages, called dinoflagellate cysts or dinocysts, as part of their life cycles.Dinoflagellates are considered to be protists, with their own division, Dinoflagellata.ost photosynthetic species contain chlorophylls a and c2, the carotenoid beta-carotene, and a group of xanthophylls that appears to be unique to dinoflagellates, typically peridinin, dinoxanthin, and diadinoxanthin. These pigments give many dinoflagellates their typical goldenbrown color.
Defenses & predators. Defenses of limpets include attachment strength, shell, escape crawling, and camouflage (both visual and chemical). Chief predators are crabs, fishes, and sea stars when the tide is in, and birds when the tide is out.There is overlap between defenses and predators.eyhole limpets Diodora aspera are often richly adorned with growths of colonial tunicates, sponges, and bryozoans. Whether this is for visual or chemical camouflage is not known. The individual in the photo on the Right seems visually camouflaged (to our eyes), but not the one on the Left.
