The Intertidal Community The intertidal zone is an environment in constant transition. Twice daily the tides move in and out. Plants and animals submerged one hour are exposed the next. Severe changes in temperature, pressure, light, salinity and oxygen content occur with each tidal shift. It’s no wonder that life at the

It has four distinct physical subdivisions based on the amount of exposure each gets -- the spray zone, and the high, middle, and lower intertidal zones. The intertidal zone, also known as the littoral zone, is that area between the high tide mark and low tide mark. Intertidal zones may be rocky, sandy or mudflats. The intertidal zone can be divided the following ‘sub-zones’ – the spray zone, upper intertidal zone, mid intertidal zone and the lower intertidal zone (Figure 2). 2019-10-10 · The intertidal zone can be further divided into three zones: high tide, middle tide, and low tide. The high tide zone is only submerged at high tide and is hotter and drier as a result.

It is a highly saline zone, making life for most aquatic plants difficult. Middle Intertidal Zone: This region is submerged under water most of the day, except during low tide. Due to this, the salinity level and temperature are lower than the higher zone. This allows for more aquatic plant growth. However, the wave action is harsher in this zone. Intertidal Zone Plants Similar to the animal species residing within the intertidal zones, the vegetation which grows within each area is dictated by the relative exposure to water during the cycle of the tides.
