The black scorpionfish is a background fish species attracted to the use of Black Sea fish community.The purpose of this work was to study the eidonomy of the black scorpionfish from the Caucasian shelf of the Black Sea, as a full-fledged study of its intraspecific variability.The morphological (plastic and meristic) parameters of black scorpionfish from three water areas of the Caucasian shelf of the Black Sea are compare in this paper. Samples from coastal waters in the areas of Bolshoi Utrish, Magri and Adler were studied in this paper. It is shown that the black scorpionfish of the water areas under consideration have very different sets of morphological features, which can be used to successfully distinguish representatives of different regions from each other.
