Cellular slime molds live near decaying substances in terrestrial habitats. Euglenoids are mainly found in fresh water; since their internal environments are hypertonic as compared to the fresh water that surrounds them, euglenoids pump out incoming water using contractile vacuoles. Ampicomplexans such as the organisms that cause malaria and toxoplasmosis are parasites that live inside of vertebrate and invertebrate hosts. Only dinoflagellates are organisms that are typically found in seawater, with some forming endosymbiotic relationships with corals.
