Facts About the Seashore (Intertidal Zone)

Dynamic environment—constantly reshaped by tides, waves, currents.
Vertical zones by submersion time: supralittoral (highest, only highest tides), mid-littoral (regular high tides), sublittoral (always submerged).
Rich biodiversity: seaweeds, sea stars, crabs, shellfish, specialized algae.
Critical ecosystem: food, shelter, breeding grounds for marine life.
Human use: swimming, fishing, boating, recreation.
Threats: pollution, climate change (sea-level rise, warming), coastal development.
Conservation essential for future ecological and human benefits.
