Intertidal ZoneThe zone between the highest and lowest
tides along marine shores.Located along coast lines all around the
world
Kathleen Fox
Three Zones Within…Supra-Littoral
Zonecovered by water
during the highest high tides
arid conditions
Mid-Littoral ZoneIncreased
submergence time Home to many
mussels Pisaster ochraceous.
Low-Littoral Zonenormally covered by
water. high concentration
of nutrients Home to many
organisms
Kathleen Fox
Organisms Adapt to Changes…Moisture
Covered at high tide, exposed to air at low tide.
Water Movementrough waves can
dislodge or carry away poorly-adapted organisms (Barnacles)
Temperaturerange from
moderate water temperature to moderate/scorching or freezing air temps.
SalinityTide pools can
become diluted or very salty
