An integrative analysis of morphological, genetic, and biological adaptations occurring in lacustrine forms of the genus\n                    <jats:italic>Triglopsis<\/jats:italic>\n                    was carried out. The obtained results demonstrate the presence of rapid adaptive changes in morphological features associated with skeletal lightening. The degree of morphological transformation varies from lake to lake, thus gradual morphological changes are observed. The diet of lake forms is dominated by crustaceans, as in marine\n                    <jats:italic>Triglopsis<\/jats:italic>\n                    , but the objects they consume gradually decrease in size. In contrast to morphological differences, populations are characterized by weak genetic differentiation from each other due to recent colonization (10\u201315 kya). However, genetic evidence of the adaptive nature of speciation processes occurring in the genus\n                    <jats:italic>Triglopsis<\/jats:italic>\n                    , which are not characteristic of Myoxocephalinae in general, was found. Methods for the detection of natural selection revealed an increase in episodic positive selection occurring in the\n                    <jats:italic>cytb<\/jats:italic>\n                    gene in species of the genus\n                    <jats:italic>Triglopsis<\/jats:italic>\n                    (as well as\n                    <jats:italic>Megalocottus<\/jats:italic>\n                    ) that successfully adapted to low water salinity.
