The island, c.7 km offshore in the Straits of Hormoz, is roughly circular and c.7 km across. Most of the shore is sand beach, but there are some rocky shores and low cliffs, and a small tidal creek system with saltmarsh vegetation just east of the main harbour. Inland are sandy plains with little vegetation other than a few scattered thorn trees, and bare volcanic hills rising to 235 m. There is one substantial fishing village and a few small settlements with small patches of irrigated cultivation and date gardens.
See boxes for key species. No proper surveys have been carried out. The island is probably an important staging and/or wintering area for shorebirds, gulls and terns, and figures are given below for a brief survey in May 1974.
