Intertidal Zone Kathleen Fox
Intertidal Zone • The zone between the highest and lowest tides along marine shores. • Located along coast lines all around the world Kathleen Fox
Types of Intertidal Zones • Sand Beaches • Rocks • Estuaries • Mangrove • Coral Reefs Kathleen Fox
Three Zones Within… • Supra-Littoral Zone • covered by water during the highest high tides • arid conditions • Mid-Littoral Zone • Increased submergence time • Home to many mussels • Pisasterochraceous. • Low-Littoral Zone • normally 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 Movement • rough waves can dislodge or carry away poorly-adapted organisms (Barnacles) • Temperature • range from moderate water temperature to moderate/scorching or freezing air temps. • Salinity • Tide pools can become diluted or very salty Kathleen Fox
Flora • Sea Grass • Seaweed • Green Algae • Dead Mans Finger • Brown Algae • Common Rockweed Kathleen Fox
Fauna • Crabs • Starfish • Atlantic Horseshoe Crab • Shiny Red Tunicate Kathleen Fox
Threats • Invasive Species • Caulerpataxifolia • Algae from Caribbean in Massachusetts • Humans • Harvesting animals/plants (aquariums: seaweeds) • Shell collecting • Pollution • Trash • Oil spills • Sewage spills • Toxic chemical runoff • Global Climate Change • Rise in ocean temperature • Shift of distribution Kathleen Fox
