Answer Details

The shoreline of a marine habitat is divided into distinct zones based on their relationship to the tides. The area described in the question - above the high tide mark, not submerged by normal tides but regularly wetted by the spray from breaking waves - is the splash zone (also called the supralittoral zone or spray zone).

The key zones from shore to deep water are:

  • Splash zone (supralittoral) - above the high tide mark; only reached by wave spray, not by normal tides. Organisms here (such as lichens, periwinkles, and some crabs) must tolerate long periods of dryness and only occasional wetting.
  • Intertidal zone (littoral) - the area between the high tide mark and the low tide mark. It is alternately submerged and exposed as tides rise and fall. Barnacles, mussels, and seaweeds are common here.
  • Subtidal zone (sublittoral) - permanently submerged below the low tide mark.
  • Benthic zone - the bottom of a body of water, not a shoreline zone defined by tides.

The question specifically states "above the high tide mark" and "wetted by spray," which precisely matches the definition of the splash zone.
