In the study, morphometric indicators of female grey seals were measured to detect changes in their size characteristics during various physiological phases of ontogenesis, including molting, pregnancy, pup and feeding in conditions close to natural. It was found that the pup itself slightly affected the growth of a Mature female seal, while feeding was the most energy-consuming, causing further deviations in the weight gain.
