The distribution and population characteristics of the potentially commercial deepwater crab Charybdis smithii were studied. The crabs were sampled during the research cruises of Fishery Oceanographic Research Vessel (FORV) SAGAR SAMPADA performed in the Arabian Sea and Bay of Bengal in 1985–1989. Samples were obtained from both pelagic and benthic zones. In the pleagic zone, the species was found almost throughout the study area with the maximum concentration in the offshore and inshore waters of the southwest coast of India. The highest densities of the benthic population were also found along the southwest coast of India (off Alleppey, 1740 kg h–1). In the benthic zone, the crab was recorded in the depth zone ranging between 60 and 356 m with a maximum average catch at 201–300 m in the Arabian Sea (23.1 kg h–1) and
