Cyprinidae

Remarks: The family Cyprinidae accounts for the majority (nine species, 39.13%), of the freshwater ichthyodiversity of Oman. All of these cyprinids invaded from Asia after the early Miocene. The cyprinids include the true barbels ( Barbinae) and labeonines ( Labeoninae). The true barbels in Oman is represented by only one species ( Cyprinion muscatense) which is distinguished by having a serrated posterior margin of the last unbranched dorsal-fin ray and a sharped edge and horny sheath lower lip. The labeonines in Oman are represented by one genus ( Garra) and eight species. Members of the genus Garra are distinguished by having a modified complex mouth structure (including a disk-like structure, which is a specialized mental lobe behind the lower jaw), and a smooth posterior margin of the last unbranched dorsal-fin ray.
