The present study updates the status about the geographic distribution of the giant river prawn Macrobrachium rosenbergii in the wild and exotic environments.So far, this species has been formally recorded in 26 countries and 1 island.For the first time, we validated the occurrence of giant river prawn in exotic environments across the ecoregions: Honshu-Shikoku-Kyushu (Japan), Western Taiwan, Eastern Taiwan (Taiwan), Guianas, Puerto Rico-Virgin Islands, and Windward and Leeward Islands (Martinique), besides new records in Ganges Delta and Plain, Northern Deccan Plateau, Western Ghats, Southeastern Ghats (India), Ganges Delta and Plain (Bangladesh), Chao Phraya, Mae Khlong (Thailand), Southern Central Sumatra, Southern Sumatra-Western Java, Malukku, Lesser Sunda Islands, New Guinea North Coast, Southwest New Guinea-Trans-Fly Lowland (Indonesia), Malay Peninsula Eastern Slope, Northern Central Sumatra-Western Malaysia, Northwestern Borneo (Malaysia), New Guinea North Coast, Southwest New Guinea-Trans-Fly Lowland (Papua New Guinea), Kimberley, Arafura-Carpentaria, Lake Eyre Basin (Australia), Amazonas Estuary and Coastal Drainages, Northeastern Caatinga and Coastal Drainages (Brazil).In addition, we confirmed the first occurrence of this species in exotic areas along the Northeastern Caatinga and Coastal Drainages ecoregion in the state of Ceará, northeastern Brazil.
