The 4 Zones of the Intertidal Zone

The Intertidal zone is split vertically into 4 different zones within. They are, the spray zone, the high tide zone, the middle tide zone, and the low tide zone.

The Splash/Spray Zone:This is also called the Upper Littoral Zone. This area of the Intertidal zone stays dry most of the day, but it is sprayed with salt water during high tide. The only time it is flooded is when there is storms or extremely high tides.

The High Tide Zone:This zone is also called the Upper Mid-littoral. This section is only fully flooded in high tide.

Middle Tide Zone:This zone is also called the Lower Mid-littoral Zone. This zone is only flooded about twice a day with salt water from the tides.

Low Tide Zone:This zone is also called the Lower Littoral Zone. This area is mostly underwater,unless the tide is unusually low, then it gets exposed to air.
