This study aimed to identify the species of sea cucumbers using SCUBA diving operations around the Qeshm island, Hamoon harbor, Simin beach, Sousa and Salkh villages in the warm (July) and cold (January) seasons in 2014 - 2015. After transferring the samples to the laboratory, identification was performed by mining spicules and the valid keys. A total of two family Holothuriidae and Stichopodidae, two genus (Holothuria and Stichopus) and 3 species including Holothuria scabra, Holothuria leucospilota, and Stichopus hermanni were identified. The highest density of species was recorded for H. Leucospilota species. All species examined in this study has a low density. The only species of sea cucumber (H. leucospilota) has high density in the studied area. So it seems that this species is the dominant species in the island.
