Mantis Shrimp Gonodactylus platysoma was observed during a survey for seaweed-related macrofauna from the intertidal region of Andamans after a century. The specimen was collected using a scoop net, identified based on Kemp (1913) and Ahyong (2001). The detailed description, images and illustrations are given in this article. The reappearance of G. platysoma after a century highlights the potential of revealing the rich biodiversity in Andaman and the need to monitor stomatopods for a better overview of their ecological interactions and diversity.
