Answer: Fish
Notes: Scientists recently discovered a new fish species named Pethia dibrugarhensis in the Brahmaputra River at Maijan in Dibrugarh, Assam. It belongs to the Cyprinidae family and is classified as a barb. It lives in moderately fast-flowing river stretches with mud, sand, and stone beds. It coexists with other small native fish species in the region. The fish has an incomplete lateral line. It shows a prominent black blotch on both the dorsal and ventral sides of the caudal peduncle. It lacks humeral marks and barbels, making it distinct from other species.
