The critical analysis of dolphins, fish and pinnipeds hydrodynamics in word-wide scientific literature for the last 70 years is presented. Biohydrodynamic researches in the former USSR and Russia are compared to the researches in other countries (including the USA). A lot of attention was paid to the investigation of thin structure of the dolphins and pinnipeds boundary layer in the former USSR and Russia. This method is essential for understanding of the dolphins hydrodynamic. Experiments of this kind haven’t been carried out in Western Countries and the USA so far. The mathematical transfor-mations and formulas to calculate the dolphins fluke model thrust and power coefficients and efficiency are presented.
