The supralittoral zone marks the upper extent of the intertidal and in some cases is considered a terrestrial habitat i.e within the EUNIS classification it is placed with the coastal habitats.
The supralittoral or 'splash zone' is the area at the top of the shore that receives the salt spray from the waves, as such, those shores experiencing greater exposure and salt spray from waves have larger supralittoral zones. Rock angle, shade and local climate also influence the extent of the zone.
The supralittoral zone is characterised by rocks covered in lichens, salt tolerant angiosperm and pools with variable salinity and temperatures. The organisms are highly specialized to endure variable salinity, periods of exposure and occasional immersion during storms.
In this example tadpoles are found in the supralittoal rockpools of the shore.
