Abstract

In this study, new occurrence of two cryptobenthic goby species belonging to genus Chromogobius in the Sea of Marmara and Turkish coast of the Black Sea are reported. While Chromogobius zebratus (Kolombatovic 1891) is a new record for the Sea of Marmara and Turkish coast of the Black Sea, the other species C. quadrivittatus (Steindachner 1863) is the first record for Turkish coast of the Black Sea. Some morphological – ecological properties of these gobies were examined. Juvenile coloration of C. quadrivittatus and differences between adults and juveniles are also described for the first time in the present study.
