Abstract

This study provides the first record of the naticid species Gennaeosinum perobliquum in Indian waters.  Previously documented from Vietnam, Indonesia, and South Africa, G. perobliquum was collected during a benthic survey, from the intertidal zone of Chandipur, Balasore, Odisha, on the eastern coast of India.  A clear description of the shell morphology is provided, along with detailed morphometric and imaging analyses. By comparing G. perobliquum with related naticid species found in India, this work aims to refine taxonomic understanding and contribute to knowledge of naticid biodiversity in the region. This newly documented record not only expands the known geographic distribution of G. perobliquum but also underscores the importance of continued benthic faunal surveys for further exploration of molluscan biodiversity in the Bay of Bengal and adjacent regions.
