【摘要】 [目的]研究缙云山3种蛇的半阴茎形态。[方法]对重庆缙云山的3种蛇类,即山烙铁头、赤练蛇、白眉腹链蛇,采用外阴茎外翻较好的标本在双目解剖镜下进行描述和绘图,少数外翻不好的情况,采用人为方法将其外翻。[结果]山烙铁头有长度大于2 cm的刺,肉眼清晰可见其形状且易数其数目,精沟也较明显;而赤练蛇、白眉腹链蛇的刺一般较小且多,肉眼一般无法辨认,且精沟不明显。[结论]为有毒蛇与无毒蛇的区分提供了参考。更多还原

【Abstract】 [Objective] The aim was to study the hemipenial morphology of three species snakes in the Jinyun mountain.[Method]The hemipenial morphology of Ovophis monticola,Dinodon rufozonatum,Amphiesma boulengeri in the Jinyun mountain of Chongqing were studied.Better use of external penile eversion of Ovophis monticola,Dinodon rufozonatum,Amphiesma boulengeri in the binocular dissecting microscope specimens were described and illustrated,a small number of valgus bad situation was used artificial means to valg.[Result] Ovophis monticola had a length greater than 2 cm tip of the gill,visible shape and the number were identified with naked eye,and precise communication was also more obvious.Thorns of Dinodon rufozonatum and Amphiesma boulengeri were generally smaller and more,shape and the number were not identified with naked eye,and precise communication was not obvious.[Conclusion] The study provided reference for make distinguish between poisionous snakes and non-poisonous snakes.更多还原
