This area can include several types of <a href="/wiki/Marine_habitat" title="Marine habitat">habitats</a> with various species of <a href="/wiki/Marine_life" title="Marine life">life</a>, such as <a href="/wiki/Seastars" class="mw-redirect" title="Seastars">sea stars</a>, <a href="/wiki/Sea_urchin" title="Sea urchin">sea urchins</a>, and many species of <a href="/wiki/Coral" title="Coral">coral</a> with regional differences in biodiversity. Sometimes it is referred to as the <i><a href="/wiki/Littoral_zone" title="Littoral zone">littoral zone</a></i> or <i><a href="/wiki/Coast" title="Coast">seashore</a></i>, although those can be defined as a wider region. </p><p>The intertidal zone also includes steep rocky <a href="/wiki/Cliff" title="Cliff">cliffs</a>, sandy <a href="/wiki/Beach" title="Beach">beaches</a>, <a href="/wiki/Bog" title="Bog">bogs</a> or <a href="/wiki/Wetlands" class="mw-redirect" title="Wetlands">wetlands</a> (e.g., vast <a href="/wiki/Mudflat" title="Mudflat">mudflats</a>). This area can be a narrow strip, such as in <a href="/wiki/Pacific_island" class="mw-redirect" title="Pacific island">Pacific islands</a> that have only a narrow tidal range, or can include many meters of shoreline where shallow beach slopes interact with high tidal excursion. The <b>peritidal zone</b> is similar but somewhat wider, extending from above the highest tide level to below the lowest. Organisms in the intertidal zone are well-adapted to their environment, facing high levels of <a href="/wiki/Interspecific_competition" title="Interspecific competition">interspecific competition</a> and the rapidly changing conditions that come with the <a href="/wiki/Tides" class="mw-redirect" title="Tides">tides</a>.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> The intertidal zone is also home to several species from many different <a href="/wiki/Phylum" title="Phylum">phyla</a> (<a href="/wiki/Porifera" class="mw-redirect" title="Porifera">Porifera</a>, <a href="/wiki/Annelida" class="mw-redirect" title="Annelida">Annelida</a>, <a href="/wiki/Coelenterata" title="Coelenterata">Coelenterata</a>, <a href="/wiki/Mollusca" title="Mollusca">Mollusca</a>, <a href="/wiki/Arthropoda" class="mw-redirect" title="Arthropoda">Arthropoda</a>, etc.). </p><p>The water that comes with the tides can vary from <a href="/wiki/Brackish_water" title="Brackish water">brackish waters</a>, fresh with <a href="/wiki/Rain" title="Rain">rain</a>, to highly <a href="/wiki/Seawater" title="Seawater">saline</a> and dry <a href="/wiki/Salt" title="Salt">salt</a>, with drying between tidal inundations. <a href="/wiki/Ocean_surface_wave" class="mw-redirect" title="Ocean surface wave">Wave</a> splash can dislodge residents from the littoral zone. With the intertidal zone's high exposure to <a href="/wiki/Sunlight" title="Sunlight">sunlight</a>, the <a href="/wiki/Temperature" title="Temperature">temperature</a> can range from very hot with full <a href="/wiki/Sunshine" class="mw-redirect" title="Sunshine">sunshine</a> to near freezing in colder climates. Some <a href="/wiki/Microclimate" title="Microclimate">microclimates</a> in the littoral zone are moderated by local features and larger plants such as <a href="/wiki/Mangrove" title="Mangrove">mangroves</a>. <a href="/wiki/Adaptation" title="Adaptation">Adaptations</a> in the littoral zone allow the utilization of <a href="/wiki/Nutrient" title="Nutrient">nutrients</a> supplied in high volume on a regular basis from the <a href="/wiki/Sea" title="Sea">sea</a>, which is actively moved to the zone by tides. The edges of habitats, in this case the land and sea, are themselves often significant <a href="/wiki/Ecosystem" title="Ecosystem">ecosystems</a>, and the littoral zone is a prime example. </p><p>A typical <a href="/wiki/Rocky_shore" title="Rocky shore">rocky shore</a> can be divided into a spray zone or splash zone (also known as the <a href="/wiki/Littoral_zone#Supralittoral_zone" title="Littoral zone">supratidal zone</a>), which is above the <a href="/wiki/Spring_tide" class="mw-redirect" title="Spring tide">spring high-tide line</a> and is covered by water only during storms, and an intertidal zone, which lies between the high and low tidal extremes. Along most <a href="/wiki/Shore" class="mw-redirect" title="Shore">shores</a>, the intertidal zone can be clearly separated into the following subzones: high tide zone, middle tide zone, and low tide zone.
