Zonation of organisms on rocky shores of Northern Jeddah

الملخص EN

The intertidal zonation of rocky shore organisms in northern Jeddah was studied.

The distribution of organisms on the shore is tide independent, and mainly affected by the degree of exposure to wave action.

No zonation patterns were recognized in protected sites.

Regardless of seasonal fluctuation in the sea level, distinctive zonation patterns were recognized all the year round, on an exposed shore.

Some ecological remarks associated with destruction of limestone cliffs and increased exposure are discussed.
