The first report of Charybdis goaensis Padate, Rivonker, Anil, Sawant & Krishnamurthy, 2010 was from Goa, India in 2010 year. Its occurrence in Indonesia is the second report in the world. The samples were harvested by a fisherman in Sibolga city and Natal district-Mandailing Natal Regency, North Sumatera. We recorded three males and ten females of Charybdis goaensis, which consists of juveniles and ovigerous females. Both sampling locations are in one coastline in west coast Sumatera which faces directly to the Indian Ocean. We assumed that the dispersal of this species through the Indian Ocean is at their larval phase.
