The ecological and behavioral features of individuals of this species in a new area of its habitat are described. The probable reason for the expansion of the range of peacock blenny in the northern direction in the Azov-Black Sea basin is the increase in winter temperatures in the Kerch Strait, resulting in favorable conditions for wintering of the species.</p></abstract><trans-abstract xml:lang="ru"><p>Приведены сведения об обнаружении морской собачки-павлина <italic>Salaria pavo</italic> (Blenniidae) в Керченском проливе (Крымский п-ов), в котором ранее её не отмечали. Описаны эколого-поведенческие особенности особей этого вида в новом участке его обитания. Вероятной причиной расширения ареала морской собачки-павлина в северном направлении в Азово-Черноморском бассейне является повышение зимних температур в Керченском проливе, в результате чего здесь складываются благоприятные условия для зимовки вида.</p></trans-abstract><kwd-group xml:lang="en"><kwd>peacock blenny <italic>Salaria pavo</italic></kwd><kwd>range</kwd><kwd>ecology</kwd><kwd>behavior</kwd><kwd>Kerch Strait</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>морская собачка-павлин <italic>Salaria pavo</italic></kwd><kwd>ареал</kwd><kwd>экология</kwd><kwd>поведение</kwd><kwd>Керченский пролив</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках реализации темы государственного задания НИЦ ПСГ Института биологии южных морей РАН № 125012100509-6 “Оценка и развитие рыбохозяйственного потенциала перспективных районов Северного Причерноморья”.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Gibson R.N. 1968.
