中文摘要：

头足类被认为是未来重要蛋白质来源之一。生殖系统是头足类的重要系统之一,不仅是生物学研究的基础,也是繁殖生物学研究的重点,且在分类学上也具有重要作用。分析认为,雌性个体的输卵管和缠卵腺在柔鱼类、枪乌贼类、乌贼类和蛸类间存在明显差别;十腕类的纳精囊位于口球内,而蛸类位于输卵管腺上;交配囊是耳乌贼亚科的特殊生殖结构,在小乌贼属的分类上具有一定意义。茎化腕是雄性头足类的重要生殖器官,也是重要的分类性状,各大类的茎化腕部位和特征有所差异;交配器为耳乌贼亚科茎化腕上的特殊结构,在分类上具有一定作用。绝大多数雄性个体的精囊结构复杂,其放射导管、连接管以及精团在帆乌贼科的分类上具有一定意义。

英文摘要：

Cephalopods is one of the most important sources of protein for human.Its reproductive system is an important part for cephalopods,not only is considered as the basis of biological study and the focus of reproductive biology,but also plays an important role in the taxonomy.For females,there are such remarkable differences as the oviduct and oviducal gland among Ommastrephids,Myopsids,Sepioids and Octopods.Seminal receptacle of Decapodiformes is located in buccal mass,but that of Octopodiformes on oviducal gland.Bursa copulatrix is one special organ in subfamily Sepiolinae to be considered as a certain role in taxonomy for genus Epietta.For males,hectocotylus is an important taxonomy characteristic and there are some differences in their locations and structures among different cephalopods.Copulatory apparatus is a special structure in hectocotylus,whose usage is also considered.The majority of cephalopods with complex spermatophore of which ejaculatory apparatus,connective complex and sperm mass are considered of certain significance at taxonomy in family Histioteuthidae,but major cephalopods with simple spermatophore is generally called sperm packet.
