Schizothorax - Marinkas (Snowtrouts)

Schizothorax is a genus of cyprinid fish found in southern and western China, through northern South Asia (Himalaya) and Central Asia, to Iran, with a single species, S. prophylax, in Turkey.

They are primarily found in highland rivers, streams and lakes, although a few species occur in lower-lying locations, like Lake Balkhash and lakes of the Sistan Basin.

The western species are typically referred to as marinkas from their Russian name marinka, while the eastern species are usually called snowtrouts. Although they do resemble trouts in habitus, this is merely due to convergent evolution and they are by no means closely related apart from both being Teleostei: Cyprinids are in the teleost superorder Ostariophysi, while trouts are in the superorder Protacanthopterygii. Their ancestors must thus have diverged as early as the Triassic, more than 200 million years ago.
