  2. What are Rocky Shores...? A rocky shore consists of rocky ledges with pools of salty water, boulders, pebbles and other non-living things such as air and sunlight. Living in this habitat is a community of hardy plants and animals; each species is specially adapted for coping with the harsh environment around it.

  3. Rocky Vs. Sandy Along the rocky coasts, organisms can attach themselves to the rock; along a sandy shoreline, there is no way for the organisms to attach themselves to the sand. Also Sandy shores tend to have very high and very low dunes.

  8. THREATS TO ROCKY SHORES! Rocky shores and the life associated with them are harmed by pollution, much of which is brought to the coast by rivers. Sewage in river water can carry cholera which is then taken up by shellfish and, when this is eaten by people, the latter can become infected. Many rocky shores are subject to indiscriminate collecting of bait, shells and rock pool life.
