- About the Intertidal Zone
- Safety

Intertidal Zone
• There are different types of reefs. The reef around North Keppel Island is a fringing reef
• We are in a green zone, which means that it is a ‘no take’ zone. This allows the area to regenerate.
Factors affecting the intertidal zone
* The intertidal zone is subject to tides and the associated physical and biological stresses of being covered with water and then exposed to air.
* The organisms living in the intertidal zone have adaptations to aid survival in their particular habitat.
• Abiotic (non-living) factors - pH - amount of light - salinity - slope - turbidity, current - wind speed - temperature
Life in the intertidal zone
• There is an amazing and diverse range of plant and animal organisms in the intertidal zone
• You might see tube worms, sea slugs, soft corals, mudskippers, algae
• If you move a rock, it must be put back exactly as it was to protect the life underneath the rock
Safety
• There are dangerous organisms in the reef.• General rule – If you are not sure, then
don’t touch it!• Beware of cone shells and a specific few corals
that can sting• Beware of oysters on the rocks, and stay away
from them as much as possible• Stay together as a group and follow teacher
instructions
