Самцы в пробе четырехкратно численно преобладали над самками; ювенильные особи не встречены. Размеры: ширина карапакса самцов составила 7,3–21,4 мм (в среднем 14,4±2,5 мм), длина карапакса – 5,5– 15,9 мм (в среднем 11,0±1,8 мм); ширина карапакса самок – 8,6–15,9 мм (в среднем 10,8±1,7 мм), длина карапакса – 6,7–12,1 мм (в среднем 8,3±1,3 мм). Среди самцов доминировали особи с шириной карапакса 13–15 мм (доля 46 %) и длиной карапакса 10–11 мм (48 %), среди самок – с шириной карапакса 10–11 мм (доля 45 %) и длиной карапакса 7–9 мм (доля 77 %). Выполненный морфометрический анализ 18 пластических признаков шести элементов экзоскелета краба определил ряд особенностей полового диморфизма вида залива: размеры большинства пластических признаков карапакса, абдомена, мерусов переоподов второй и третьей пары, правой и левой клешней у самок были на 12–49 % меньше, чем у самцов (исключение – четвертый сегмент абдомена – он был шире у самок на 45 %). Отмечены и черты сходства для крабов обоих полов: размеры правой клешни были достоверно больше размеров левой клешни, что связано с функциональной специализацией клешней. Сравнительный анализ с данными морфометрии для вида залива десятилетней давности позволил предположить достаточную стабильность размерной структуры и морфологии экзоскелета особей краба Харриса из поселений в Таманском заливе.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the features of sex and size composition, morphology of the crabs Rhithropanopeus harrisii from Taman Bay collected in July 2021. In the sample, males outnumbered females fourfold; juveniles were not encountered. Sizes: the carapace width of males was 7.3–21.4 mm (on average 14.4±2.5 mm), the carapace length was 5.5–15.9 mm (on average 11.0±1.8 mm); the carapace width of females was 8.6– 15.9 mm (on average 10.8±1.7 mm), the carapace length was 6.7–12.1 mm (on average 8.3±1.3 mm). Among males, individuals with a carapace width of 13–15 mm (46 % share) and a carapace length of 10–11 mm (48 %) were dominant, while among females, those with a carapace width of 10–11 mm (45 % share) and a carapace length of 7–9 mm (77 % share) were dominant. A morphometric analysis of 18 plastic characters of six elements of the crab's exoskeleton revealed a number of features of sexual dimorphism in the species of the Gulf: the sizes of most plastic characters of carapace, abdomen, merus of pereiopods 2 and 3 and of the right and left claws were 12–49 % smaller in females than in males (the exception was the fourth abdominal segment, which was 45 % wider in females). Similarities for crabs of both sexes were also noted: their right claw was significantly larger than the left claw, reflecting the functional specialization of the claws. A comparative analysis with morphometric data for R. harrisii of that Bay from a decade ago suggested a relatively stable dimensional structure and exoskeleton morphology in Harris crab specimens from Taman Bay settlements.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Rhithropanopeus harrisii</kwd><kwd>Таманский залив</kwd><kwd>половой состав</kwd><kwd>морфометрия</kwd><kwd>размеры</kwd><kwd>половой диморфизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Rhithropanopeus harrisii</kwd><kwd>Taman Bay</kwd><kwd>sex ratio</kwd><kwd>morphometry</kwd><kwd>sizes</kwd><kwd>sexual dimorphism</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">авторы выражают благодарность сотрудникам Института океанологии имени П.
