<em>Cyprinus acutidorsalis</em> is a brackish-water fish of the family Cyprinidae, belonging to the genus that includes the common carp. This species can reach a maximum recorded length of approximately 27 cm and a maximum weight of approximately 0.5 kg. As a brackish-water cyprinid, <em>Cyprinus acutidorsalis</em> occupies the transitional zones where freshwater rivers and streams meet coastal or estuarine environments, tolerating elevated salinity levels uncommon among most members of its family. The specific epithet "acutidorsalis" suggests a distinctively acute or sharply angled dorsal profile. Cyprinids in brackish habitats typically feed opportunistically on organic matter, small invertebrates, and plant material available in their estuarine environment. Details of specific habitat associations and the precise geographic range of this species remain limited in the ichthyological literature.
