介绍: 红螯螯虾整个躯体由体表被覆几丁质甲壳的头胸部和腹部组成,全身有20节,头胸部13节。头胸甲保护着内脏器官,头胸甲前有一向前延伸的额剑,两边各有3~4个棘。头胸甲背部有4条沿身体纵轴方向排列的脊。双眼有柄而突起。头胸部有5对步足,第1对为粗壮的大螯,雄性的大螯在外侧有一膜质鲜红美丽的斑块,第2、第 3对步足为螯状,第4、第5对步足为爪状。腹部有7节,虽被覆甲壳,但节间关联处有纤维膜相连,可灵活运动。腹部第2节至第5节下面都有1对附肢,称为腹足或游泳足。腹部第6节附肢向后伸展,加宽称尾足,并与尾节组成尾扇,是螯虾快速运动器官。在头胸部的前端还有3对触角,1对大触角,2对小触角。 红螯螯虾在河流、湖泊、水库、池塘都能生活,白天潜伏在水体中可隐蔽的地方,傍晚和黎明前出来觅食,喜夜晚活动,营底栖爬行生活。常在砖瓦、砾石的间隙中爬行或潜伏在池塘的天然洞穴及人工洞穴中,在较软的池底中有掘穴能力。有时亦沿池壁上爬或攀伏于水生植物的根和密叶中。 |
