coastal.er.usgs.gov — Coral microbial ecology is the study of the relationship of coral-associated microorganisms to each other, the coral host, and to their environment. Just as we humans have beneficial bacteria living on our skin and in our intestines, corals also have co-habitating non-pathogenic (not disease-causing) microbes. These microbes include bacteria, More...
