Zonation on a rocky shore
The seashore is a habitat that contains a wide range of microhabitats and ecological niches for different creatures. This is mainly due to the effects of the tides, that rise and fall twice each day.Tides are the vertical movement of water in a periodical oscillation of the sea, due to the gravitational pull of the sun and moon. The tides are on a semi-diurnal cycle, so there are two high tides and two low tides each day. Due to the orbit of the moon, the tides also have a monthly cycle. This creates neap (very low) and spring (very high) tides. The seashore can be divided into several zones, which are illustrated on the diagram below: This is the highest zone on the shore, and lies above the EHWS mark, and therefore is never covered by seawater. However, it may be occasionally be spray wetted. Because of this, it is ma
