Abstract:	In the Polish costal zone of the Baltic Sea two similar looking gobies – sand goby and common goby occur. In quantitative investigation both species are often taken as an one, because of difficulties in distinguish them. There are a few methods to differentiate sand goby and common goby - body pigmentation, shape of head and pigmentation of a spleen (Ławacz 1965). During the investigation it was proofed that compared species differ from each other also in biological characteristic. In the Gulf of Gdańsk spawning-season starts for sand goby in March and ends in September, for common goby it lasts from March to August. They have different sex ratio, but they have similar range of a HSI and GSI coefficients. Those differences and similarities are important for future investigations because they show that sand goby and common goby should be separated in studies.
