Rocky shores are one of the most important habitats of marine environment in coastal areas. This study was done in 2010-2011 to investigate the diversity of true crabs in intertidal rocky shores of Qeshm island. Samples were collected from intertidal zones during the low-tide at 5 stations. The specimens were fixed in 70% Etanol and transferred to laboratory for identification. Altogether, 15 crab species belonging to 8 families and 14 genus were identified. 4 species were from Portunidae, 3 species from Eriphiidae, 2 species from Majidae,2 species from Grapsidae were identified. The others families including Euryplacidae, Leucociidae, Pilumnidae and Xanthidae families have the lowest species richness with only 1 species per family. Portunidae family with 4 species in intertidal zone had the highest species richness amongst studied stations. 3 species of Eriphia smithi from Eriphiidae family, Leptodius exaratus from Xanthidae family and Thalamita crenata from Portunidae family were present at all three intertidal zones (High tide, Mid tide and Low tide).

Total Petroleum Hydrocarbon ( TPH ) are environmental contaminants that are released into the marine environment through oil spills, industrial and domestic activities. TPH are readily transformed into more hydrophilic metabolites, which are accumulated in bile. Thus fish bile can be used as a biomarker of exposure of fish to TPH in the marine environment. in this study several stations were selected from the Khure Mussa in the northern part of the Persian Gulf. Fish and sediment sampling were collected in the 2009. Preparation and analysis of the samples were performed according to MOOPAM method using Spectro florophotometer (UVF(. The highest average concentration of TPH in sediment was 364.91 mg/kg (dry weight) and was observed in Jafari station. The maximum concentration of TPH in bile liquid of fish (Euryglossa orientalis ) was 525 mg/l which was found in Zangi station. Statistical analysis revealed a significant differences between TPH concentration in sediment and in bileliquid of fish (Euryglossa orientalis ) in the study area (Pfish bile observed in this study suggests that fish bile can be used as a tool for bio-monitoring of TPH pollution.
