First record of sponge distribution in the Persian Gulf, (Hengam Island, Iran).
The present study is a first attempt to examine sponge distribution in the Persian Gulf (Iranian costs) and suggests that physical and biological factors influence the sponge distribution patterns in Hengam Island. The purpose of this study is to provide patterns of sponges distribution and depth influence on sponge abundance and biomass on the Hengam Island. Surveys of sponge distribution were conducted June 2006 and February 2007 at 5, 10, 15 and 20 m depths sites in two locations: East and West of the Hengam island. Abundance and biomass of sponges species were surveyed at different depths on the Hengam Island in the Persian Gulf. All data on sponges species number and abundance and biomass in each region of Island were taken by SCUBA diving. Transect sampling in this area revealed distribution of sponges species. The sponges species in this area consist of Callyspongia clavata, Callyspongia vasselli, Hyrtios erectus, Haliclona sp., Leucetta sp., Ircinia echinata and Dysidea cinerea. Abundance and biomass of sponges in Hengam Island increased at 15-20 m depths.
