Paperpencil.gif (4347 bytes) Types of Reefs: #5

Fringing reefs Reefs that form along a coastline.
They grow on the continental shelf in shallow water.
Barrier reefs Grow parallel to shorelines but farther out.
Usually separated from the land by a deep lagoon.
Form a barrier between the lagoon and the seas impeding navigation.
Coral Atolls Rings of coral that grow on top of old, sunken volcanoes in the ocean.
They begin as fringe reefs surrounding a volcanic island. 
Then, as the volcano sinks, the reef continues to grow.
Eventually only the reef remains.

Lecture.gif (2227 bytes) Reefs at Risks
Explain the scenarios are factual.
Read the following scenario to the class.


Over fishing in the Philippines, Guam, and Indonesia has caused the disappearance of red snapper and giant grouper from entire areas. Without these predators in the area, the sea urchin population has increased. Sea urchins kill live coral as they feed on algae. Eventually, algae growth overtakes the coral, and new polyps cannot grow. Explain the effect these changes might have on the food web you have made.

State what the problem is.
Over fishing

Name the populations that will decrease.
Red Snapper and Grouper will decrease.
Coral will decrease.
Algae will decrease

Name the populations that will increase.
Sea urchin

Will the reef survive?
