Telescopium telescopium is an intertidal gastropod which is abundantly distributed in the mudflats of Sundarban estuary of India. They play a vital role in the fragile ecosystem of Sundarban mangroves. These hard shelled molluscs are mud creepers and feed on the algal mats of the estuary. Motorized boats run by diesel are the chief mode of transport for the human population of this geographical region. A good number of such boats regularly ply along the creeks of Sundarban estuary for various purposes. Occasional spillage of diesel from these boats causes contamination of water and soil of this ecosystem. Telescopium telescopium along with other benthic organisms are chronically exposed to this vehicular diesel. Present study reports histopathological alterations of gills, digestive gland and mantle of Telescopium telescopium treated with environmentally realistic concentration (0.15%) of diesel for a period of 15 days. Histopathological damage of vital organs like gills, digestive gland and mantle render this species vulnerable to the risk of population decline in its natural habitat.
