Özet
In this study, some morphological and anatomical characteristics of Silurus triostegus from Tigris and Euphrates Rivers and Silurus glanis from several lakes and Rivers of Turkey were investigated. Although, S. Triostegus has two mandibular barbels, usually in the young specimens there are four mandibular barbels, sometimes 3 mandibular barbels. This situation may show that some mandibular barbels reabsorbed. Maxillary barbels of S. glanis reach to the end of the pectoral fin, but those reach to only middle of pectoral fin in S. triostegus. Also, anterior mandibular barbels of S. giants shorter than posterior ones, but when two pairs of mandibular barbels are present in the S. triostegus, the anterior ones are always longer than posterior ones. The pectoral spine, vomerine teeth band, some cranial bones such as basioccipital, supraoccipital and mesethmoid show some difference between the two species.
