8 Ocean Zones & Marine Ecosystems Note Guide 9

Marine Vocabulary Swim 10

Intertidal ZoneShoreline area that falls between the high tide and low tide mark.

Life in the Intertidal ZoneAnimals in this area are able to adapt to being both underwater and in open air

Common Life Forms:

CrabsUrchinsStarfishClamsSnailsMussels

Neritic ZoneThe ocean zone that slopes down from the shoreline towards the ocean floor.

Life in the Neritic ZoneAnimals in the

Neritic Zone have access to both shallow and deeper water. The life in this zone is very diverse!

Common Life Forms:

Sea Turtles DolphinsSealsVariety of fish

Oceanic ZoneThe oceanic zone is made up of the open waters of the ocean

Life in the Oceanic ZoneMarine life varies

greatly due to the changes in depth, temperature, pressure and amount of sunlight.

Common Life Forms:

WhalesSharksSquidAngler Fish

Marine Ecosystems:Within these zones

are many different and separate ecosystems.

Coral ReefsExtremely diverse ecosystems - “The Rainforests of the Ocean,” are sensitive to change and protect coastlines from storm surges

EstuaryAn area where fresh water from a river mixes into the salt water of the ocean creating “brackish” waters

Estuary DemoSalt Water is denser than freshwater therefore it does not fully mix…watch what happens in our mini estuary

Kelp ForestsLarge underwater forests of brown algae that provide a habitat for animals and many resources for humans

Salt MarshesA transitional area between land and water that acts like a filter for pollution

Mangrove ForestsA transitional area between land and water in tropical areas that transfer energy from land to sea through the food chain
