Deeper water rock, sheltered from waves and currents

 

Seaweeds need sunlight to grow, and are confined to shallower water.  Below the main kelp zones animal communities will tend to dominate, although encrusting red seaweeds can remain a prevalent species into deeper water in rocky areas where the waves and currents are weak.

These areas are also home to sea squirts, dead man’s fingers and plumose anemones.  The smooth muddy tubes and ornate feathery tentacles of peacock worms and bristleworms, also occur in these environments, and squat lobsters and hermit crabs, as well as urchins and starfish, can form part of the community of marine life.
