Abstract: There are more than 500 species of echinoderms as an important marine fishery stocks in China，especially sea cucumbers and sea urchins which are important aquaculture species known as the eight treasures of seafood.Most of echinoderms have no obvious sexual dimorphism in appearance.However, there are significant difference in gonadal color immunocompetence and sex hormone levels in female and male.Therefore, it is of great theoretical and economic significance to study the sex determination and sexual differentiation mechanism of echinoderms and realize unisexual breeding.In this article，reproduction strategies, and genetic basis of sex determination and sexual differentiation of economically important echinoderms(sea cucumbers，sea urchins)are summarized, and suggestions on the determination of sex chromosomes in echinoderms, development of sex-linked molecular markers, application of gene editing technology and sex hormone-induced unisexual culture are put forward to provide valuable references with promotion of the sex control breeding of economically important echinoderms.
