Definition of Intertidal Zone
The intertidal zone is such a region where the ocean and the land meet. This zone extends over hundreds of meters. The intertidal zone is being divided into four divisions. All the divisions are different in terms of ecology and they have distinct characteristics. The four divisions are the spray zone, high intertidal zone, middle intertidal zone, and low intertidal zone.
The creatures present in the sea arrange themselves according to their abilities such as to compete for space, to avoid predators, and to resist dryness. The larger marine organisms hunt for food at high intertidal zones whereas the birds present near the shore look for food at low intertidal zones.
