The research aimed to find out the various kind ridge of rock, especially Anthozoa classes existed in the water region of Gelung village beach, what kind of ridge of rock, especially Anthozoa class dominated Gelung village beach and what kind of various ridge of rock, especially Anthozoa claas in the beach region of Gelung village Situbondo. The research used descriptive method. Location and time of the research were done in beach region of Gelung village Panarukan sub-district Situbondo from January 7th to 14th 2008.

In this research, data from the observation location was found by three phases: sample location research consideration, sampling phase, sample identification. The result was analyzed by these equations: variability (H? : -Pi log Pi where Pi : ni/n), abundance:  individual of a species/species total observation, relative abundance:  individual abundance of a species/total of all species abundance x 100%. The research concluded that Anthozoa classes in Gelung Village Situbondo beach found 12 Anthozoa classes ridge of rock and the highest species was Acropora humilis from famili Acroporidiae and the lowest species was Fungia sp from famili Fungiidia.
