The mudflat habitat is an enclosed coastal area with fresh and saltwater saturated sediments. Mudflats appear barren but conceal a rich variety of life.Many animals depend on this fragile and threatened habitat.Commercially important fish, such as the California halibut, use this habitat as a nursery ground which provides protection and a rich source of food. The area surrounding the upper part of the mud is called the saltmarsh and teems with plants.Marsh plants provide shelter and living space for other organisms. The breakdown and decay of these plants produce organic debris which is a rich food source for a variety of invertebrates, like fiddler crabs and amphipods.These animals are an attractive food source for the mudflat s large bird population, including the willet and snowy egret.any animals depend on this fragile and threatened habitat.
