小龙虾（学名：procambarusclarkii）：是甲壳纲、十足目、螯虾科水生动物。小龙虾通常携带肺吸虫，也称克氏原螯虾、红螯虾和淡水小龙虾。形似虾而甲壳坚硬。成体长约5.6-11.9厘米，暗红色，甲壳部分近黑色，腹部背面有一楔形条纹。幼虾体为均匀的灰色，有时具黑色波纹。螯狭长。甲壳中部不被网眼状空隙分隔，甲壳上明显具颗粒。额剑具侧棘或额剑端部具刻痕。
是淡水经济虾类，因肉味鲜美广受人们欢迎。因其杂食性、生长速度快、适应能力强而在当地生态环境中形成的竞争优势。其摄食范围包括水草、藻类、水生昆虫、动物尸体等，食物匮乏时亦自相残杀。小龙虾近年来在中国已经成为重要经济养殖品种。在商业养殖过程中应严防逃逸，尤其是严防逃入人迹罕至的原生态水体。其对当地物种生态竞争优势而导致破坏性危害。
