桡足纲桡足纲Copepoda甲壳动物亚门的一纲。全世界已知约有8400种，中国已发现淡水300余种，海洋约500种。桡足类身体一般1～4毫米。由16～17个体节组成，由于愈合，一般不超过11节。体躯分为前体部和后体部，其间有1活动关节。前体部较为宽大，包括头部和胸部。头部一般由6个头节与第一胸节(或第一、二胸节)愈合而成。背面有1个单眼或1对晶体。其腹面有6对附肢。胸部有3～5个自由体节，各有1对胸足，第5对胸足有显著雌雄区别。后体部(又称腹部)较短小，由3～5节组成，雌性第一、二节愈合。雄性第一腹节为生殖节，末节最小，因具肛门，称为肛节，其末端有1对尾叉。雌雄异体。少数寄生种类为雌雄同体。一般进行两性生殖，少数营孤雌生殖。雌雄异形。寄生种类雄体极小，常附着于雌体生殖器官附近。营自由生活的桡足类栖息于各种不同的水域，在世界各海洋、各种淡水水域苔藓植物丛，潮湿的树皮上或叶腋中都有分布。寄生种类多见于鱼的体表、鳍、鳃、鼻孔、口腔或眼眶等处。淡水桡足类和个别海洋桡足类有休眠现象。桡足类的食性多样化，有滤食型、掠食型、刮食型和混合型。浮游桡足类是很多经济鱼类的饵料。因此，可以根据某些浮游桡足类的数量分布来寻找渔场，还可以根据很多桡足类的分布情况探索海流的流向和测定水体污染的程度。淡水桡足类中的某些掠食性种类侵袭鱼卵或鱼苗，给鱼类的繁殖带来危害。有些淡水种类是寄生蠕虫(吸虫、绦虫、线虫)的中间宿主。还有不少种类直接寄生于鱼类和无脊椎动物体表或消化道内，危害寄主的繁殖和发育。该纲分7个目：哲水蚤目、剑水蚤目、猛水蚤目、怪水蚤目、瘤水蚤目、颚虱目和鱼虱目。
