| 摘 要： | 灰麝鼩（Crocidura attenuata）和黑线姬鼠（Apodemus agrarius）在四川南充地区有相似的生活环境，但食性迥异．本文对二者的消化道进行了初步的比较解剖研究，发现二者存在显著差别：灰麝鼩无盲肠，消化道总长仅为黑线姬鼠的一半，胃壁薄；黑线姬鼠具盲肠，胃壁厚，从外观上可区分为两部分．同时二者口腔中的牙齿、上腭和舌的形态也有较大的差别．这些差异反映了两物种的消化道形态结构是与其食性相适应的．

| Abstract: | Both Crocidura attenuate and Apodemus agrarius inhabit in the similar enviroment in Nanchong area,Sichuan but their feeding habits are quite different from each other.A preliminary comparative anatomic study on digestive tracts between the two species has been carried out.The results show that there are significant distinctions between them:There is no cecum in Crocidura attenuate.The digestive tract of it is as long as half of that in Apodemus agrarius.Its stomach wall is thin and soft.However,there is a c... |
