Estuaries
•Wet lands found where rivers meet the sea. Contain both fresh and salt H2O. They support a large number of animals

Mangrove swamps
Costal wet lands in tropical regions in Florida , Hawaii Have salt tolerant trees called mangroves.Largest in America is the Everglades in FloridaThey provide protection to many animals.
Mangrove swamps
Classification of marine ecosystemAre divided by distance from the shoreIntertidal- extreme change in H2O exposed to air and temperature Coastal- shallow photosynthetic sea life ( kelp forest) coral reefs are in this regionOpen- ocean- occurs 90% surface area of world’s oceans, low levels of nutrientsBenthic zone- is in open ocean floor
