Coral Reefs the “rainforest” of the sea
Home to the phylum  cnidaria   -  radially symmetric  (arrangement of body around a center point)  ,[object Object],[object Object],[object Object],[object Object]
Platform Reefs ,[object Object],http://oceanworld.tamu.edu/students/coral/coral2.htm
[object Object],[object Object],[object Object],[object Object],Fringing Reefs:
Fringing Reefs ,[object Object],-Most common type -This reef is attached, lying adjacent to the shore of a continent or island.  -There is little to no lagoon (a body of water cut off from a larger body by a reef of sand or coral) between it and the shore
The Barrier Reef - serve as a barrier between the ocean and the land. They slow down the harsh waves,  protecting  the coast.  -usually a wide, deep lagoon separating the reefs from the land mass.  - only grows where there has been a change of sea level on the adjacent coast  PICTURE: The Great Barrier Reef. It is located  off the northeast coast of  Australia . It measures up to  150 km long .

LOCATIONS & REQUIREMENTS FOR GOOD HEALTH
Coral Reef Locations ,[object Object],[object Object],[object Object]
[object Object],[object Object],[object Object]
wave action Coral Reefs need: warm, clear water sunlight calcium
Coral reefs have a symbiotic relationship with a type of microscopic algae, which require sunlight. Therefore, coral reefs must exist where sunlight penetrates so that they can thrive and grow. CORAL REEFS NEED: sunlight
Clear water allows for sunlight to reach the algae CORAL REEFS NEED: clear water
73-77°F (23-25°C) CORAL REEFS NEED:  warm water
waves bring in food, nutrients and oxygen to the reef  CORAL REEFS NEED: wave action
CORAL REEFS NEED: calcium used to build their limestone skeletons available in shallow waters
 
Importance of Coral Reefs and Symbiosis
Importance of Coral Reefs
Protect coasts from strong currents and waves by slowing down the water before it gets to the shore; hence the name “barrier reefs”

Reefs help local economies through tourism, diving tours, fishing trips, hotels, and restaurants

Plankton Eaters There are many fish that feed on plankton. They include damselfish, wrasses, and groupers, just to name a few. Damselfish wrasses wrasses Groupers
There are also herbivore, invertebrate, omnivore, and piscivores fish.   Herbivore fish Invertebrate fish Omnivore fish Piscivores   fish
