Estuaries are protected from the full force of the ocean by mudflats, sandspits, and barrier islands. Multi-species test batteries that include organisms from different trophic levels in addition to resident benthic communities are recommended and used in a number of studies ( Table 3 ). Their ability to beak down leaf detritus was determined when alone and when they were together. Geographical features such as reefs, islands, mud, and sand act as barriers from ocean waves and wind.Types of EstuariesThere are four different kinds of estuaries, each created a different way: 1) coastal plain estuaries; 2) tectonic estuaries; 3) bar-built estuaries; and 4) fjord estuaries.Coastal plain estuaries (1) are created when sea levels rise and fill in an existing river valley.
