The Intertidal Rocky Shore of Caloundra Beach

The five main areas of rocky coast are Shanghai coastal area, upstream coastal area, central coastal area, downstream coastal area and subshore area. Each region contains unique indicator species, so you can identify different regions more accurately. The indicator species found in our study were nodular Tunnitzia cinerea, blue gray Tunnitzynis chinensis, 6 plate acorn frondos and green / brown algae. The intertidal zone of rock is one of the worst environments on Earth.

The intertidal zone is the place where you encounter the land where the ocean flooded, and waves and tides go in and out at other times. As a result, the community is constantly changing. On coasts with many rocks, this area overlaps vertically. There are only a few kinds of algae and molluscs in places where the climax will reach. Normally, there are more kinds of algae and small animals such as herbivorous snails, crabs, starfish, small fish, etc. in the area that is flooded at high tide. Many invertebrates, fish and algae are found at the bottom of the intertidal zone exposed only at low tide. The intertidal zone of the sandy beach is not stratified like the rock band. The waves keep moving soil and sand. Therefore, there are few algae and plants that can make them, such as insects, crickets, predator crustaceans, crabs, and kishi birds.

 Intertidal zone boom: the intertidal zone boom is designed to seal the water / coastline interface. Usually, one end of this boom is fixed to a dry coast. The boom extends from the coast, goes through the water and floats on the water. This boom is at the bottom of the exposure as the water level goes down as the tide draws. When the tide enters prosperity, it floats again. Therefore, when water enters and exits, oil above water can not bypass the edge of the coastline. Water is ballast water commonly used in such booms.
