1. Rocky Intertidal

3. Intertidal Zonation
Zonation is a vertical banding of the organisms living on the rocky coastline.
These distinct bands occur in part from many complex physical and biological factors that effect marine organisms.

4. Mostly shelled orgs
Spray or Splash Zone
High Tide Zone
Middle Tide Zone
Many soft bodied orgs and algae
Low Tide Zone

5. that affect the organisms residing in the intertidal zone?
What are some stresses
that affect the organisms
residing in the intertidal zone?

6. Biotic factors affecting organisms living in the intertidal zone:
Competition for space and food
Predation
Reproduction
Substrate settlement preference
Osmoregulation (dessication)

7. Abiotic factors affecting organisms living in the intertidal zone:
Salinity
Temperature
Air and light exposure
Tidal flow
Waves and current action
Substrate
Wind direction and strength
Dissolved O2
Storms
Natural Disasters

adaptations to living
in the intertidal zone?
