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

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
