      Abstract
      Udang air tawar merupakan kelompok Crustacea dari infraordo Caridea yang memiliki keanekaragaman tinggi dan tersebar luas di berbagai habitat perairan. Pulau Sumatra, termasuk wilayah Sumatra Barat, memiliki sungai yang bermuara di Timur dan Barat Pulau sumatra yang tidak pernah bersatu sehingga memiliki menarik untuk di eksplorasi. Penelitian ini bertujuan untuk mengidentifikasi dan mendeskripsikan udang air tawar yang ditemukan di sungai wilayah Sumatra Barat yang bermuara di barat dan timur Pulau Sumatra serta mendeskripsikan karakteristik habitatnya. Sampel dikumpulkan menggunakan metode purposive sampling , kemudian dipreparasi dan diidentifikasi berdasarkan karakter morfologi. Sampel yang didapatkan teridentifikasi dalam delapan spesies yaitu Caridina gracilipes, C. sumatrensis, C. weberi, Macrobrachium lar, M. latidactylus, M. lanchesteri, M. cf. pilimanus 1 dan M.cf. pilimanus 2. Tujuh dari delapan spesies di temukan pada (Daerah Aliran Sungai) yang bermuara dibarat dengan karaktersitik subtrat bebatuan dan memiliki tumbuhan riparian. M. cf. pilimanus 1 dan 2 merupakan spesies yang memiliki karakter kunci dari M. pilimanus, namun terdapat perbedaan jelas pada jumlah gigi rostrum dan bentuk chela.
       
      Freshwater shrimps are a crustacean group within the infraorder Caridea, exhibiting high diversity and widespread distribution across various aquatic habitats. Sumatra Island, particularly the West Sumatra region, features river systems that drain into the eastern and western coasts of the island without ever converging, presenting an intriguing area for exploration. This study aims to identify and describe the freshwater shrimps found in the rivers of West Sumatra that flow into the western and eastern coasts, as well as to describe their habitat conditions. Samples were collected using a purposive sampling method, subsequently prepared, and identified based on morphological characteristics. The obtained samples were identified as eight species: Caridina gracilipes, C. sumatrensis, C. weberi, Macrobrachium lar, M. latidactylus, M. lanchesteri, M. cf. pilimanus 1, and M. cf. pilimanus 2. Seven of the eight species were found in the western-flowing watersheds, which are characterized by rocky substrates and the presence of riparian vegetation. M. cf. pilimanus 1 and 2 exhibit the key characters of M. pilimanus, but show distinct differences in the shape of the chela and the number of dorsal rostrum teeth.
