Tostudy thedistribution anddiversity ofhardcoralsafter theprimitive studiesinChabaharBay with fieldworks in 1387, fourpointswereselectedas astation. 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. One –way ANOVAtestin the range of3-2mdepthbetweenstationsLyparand Beheshti in coveragerate ofthe speciesshowedsignificant differences(p<0.05)butin the range of8-5mdepthstationswere withoutsignificant.
