This document describes a study that identified 7 species of amphipod crustaceans found in the mangroves of Pondicherry, India. The study involved collecting samples from 4 stations in the mangroves between 2008-2009 and identifying the amphipods. It describes the 7 identified species and provides details on their morphology, distribution, and habitat. The study suggests the amphipod diversity in these mangroves is relatively low compared to other areas in India and that further surveys are needed to better understand the biodiversity processes involving these crustaceans.
