Cato Reef Cato Reef Cato Reef, a part of the Cato Bank, is an area in the Coral Sea off the central coast of Queensland, Australia that is of approximately 21 km by 13 km of this 200 km area, where depth of water is typically less than 17 m. Upon Cato Bank Cato Reef encircles an area of 3.3 km by 1.8 km, area 5 km including a small shallow lagoon which contains Cato Island, a low-relief cay in the west that is approximately 650 by 300 m, area 15 hectares, 6 m high.

Coral reef Sea they consume about 60% of the phytoplankton that drifts by. Sponges eventually excrete nutrients in a form that corals can use. The roughness of coral surfaces is key to coral survival in agitated waters. Normally, a boundary layer of still water surrounds a submerged object, which acts as a barrier. Waves breaking on the extremely rough edges of corals disrupt the boundary layer, allowing the corals access to passing nutrients. Turbulent water thereby promotes reef growth. Without the access to nutrients brought by rough coral surfaces, even the most effective recycling would not suffice. Deep nutrient-rich water entering coral
