    These distinct bands occur in part from many complex physical and biological factors that effect marine organisms.

  • Spray or Splash ZoneHigh Tide ZoneMiddle Tide ZoneLow Tide ZoneMostly shelled orgsMany soft bodied orgs and algae

  • Biotic factors affecting organisms living in the intertidal zone:

    Competition for space and foodPredationReproductionSubstrate settlement preferenceOsmoregulation (dessication)

  • Abiotic factors affecting organisms living in the intertidal zone:SalinityTemperature Air and light exposureTidal flowWaves and current actionSubstrateWind direction and strengthDissolved O2StormsNatural Disasters
