Motile aquatic organisms, such as fish and crabs, follow this same pattern when moving onto and off of the marshes during high tide. The rising and falling tides make the steep creek banks and levees available as feeding and refuge sites to them and to those organisms which do not move out of the creeks. In spite of the large tidal amplitude, there are still extensive areas of marsh which are flooded only at spring tide and even more extensive areas which, although flooded daily, are submerged for very short periods of time. Thus the tidal regime maintains a diversity of habitats in the intertidal area. |
