Intertidal ZoneSlide3
Where in the world is it found?
Intertidal zones are found where
the land and sea meet, between the high and low tide zones. This complex marine ecosystem is found along coastlines
worldwide.Slide4
Intertidal Zone Abiotic Factors
Because of tides, there are huge
daily changes in moisture, temperature, turbulence (from the water), and
salinity (amount of salt).
This
biome is
rich
in nutrients and
oxygen.Slide5
Native PlantsSlide6
Native Plants
Seagrasses are grass-like flowering plants that live completely submerged in marine and estuarine
waters.
Marine algae is also known as seaweed and comes is hundreds of varieties. Slide7
Native AnimalsSlide8
Native Animals
The
sea anemone is a predatory animal that looks like a flower and lives on the ocean floor.
Bivalves are soft-bodied animals that are protected by two hard shells, hinged together. Scallops, oysters and clams are bivalves.
Hermit crabs are crabs that lack a hard shell; they use a discarded shell for protection.Slide9
Plant Adaptations
Many plants can adapt to varying levels of salt in the water and high changes in temperature that happen every day. Slide10
Animal Adaptations
Most intertidal animals have a hard outer shell or exoskeleton to ensure they aren’t crushed by the rough tides. Slide11
Symbiotic Relationship in Intertidal Zones
Limpet (small clam-like organism) and coralline crust algae
The limpet gets a constant source of food and a smooth surface to feed from. The algae benefits by having its surface cleaned by the limpet. Without the limpet,
coralline crust algae
would suffocate under debris and faster growing algae would overtake its
space. This is an example of mutualism.Slide12
Where’s the party? There are LOTS of recreational activities here!
If you’re looking for fun, come to the intertidal zone!
If you want to see a unique marine ecosystem with tons of critters, you’ve come to the right spot. Unfortunately, people have negatively impacted this biome with direct pollution and introduction of invasive species. Most intertidal zones are protected areas or nature preserves that people can’t disturb. Slide13
Famous Intertidal Zones

Environmental Threats
Visitors
: People
are one of the biggest threats to the intertidal zone, as tide pools are popular attractions. The
overall impact
of people exploring tide pools and stepping on organisms and their habitat, and sometimes taking creatures, has resulted in a decrease in organisms in some areas
.
Coastal Development:
Pollution and runoff from increased development can damage tide pools through the introduction of contaminants.Slide15
Endangered Species

Why should we care?
Although
intertidal zones represent
only a very small proportion of the Earth's surface, they're important because they're regions in which two very different types of environment meet, and in which a complex web of interactions takes place
.
Rocky intertidal
shores
support
an enormous range of life. Rocky-shore
animals and plants have
an increasingly harder time the further they are from the sea, since they rely on seawater and most are unable to move with the tides.
Seaweed thrives here and many animals survival is dependent on seaweed for food.
