Usingline transect method,data from therange of3-2mand8-5mdepthwere collected. Mostly beaches in gulf were sandy and muddy-sand and rocky bottoms that recorded corals were in the southeastern. Aftersampling20 speciesfromninefamilies were identified,except forstation4 (TIS), the4 specieswere recorded, most specieswereseenatotherstations. Faviidae family had thegreatest number ofspecies, inStation3 (Lipar) and  hada high coral coverage.
