梵净山峨眉髭蟾蝌蚪外部形态特征研究
|
摘要
为保护梵净山珍稀动物峨眉髭蟾并研究其分布及多样性,对梵净山峨眉髭蟾蝌蚪的形态进行研究。发现梵净山峨眉髭蟾蝌蚪体型肥大,其采集样本蝌蚪中体长最长的达到95mm,外形独特,其显著特征为蝌蚪体背与尾基交界处有一醒目的浅色"Y"型淡斑,口器外部形态结构简单,其唇齿式多为:I:5-5/5-5:I和I:5-5/4-4:I。
This article, to protect Vibrissaphora Boringii Tadpole, a precious and rare animal in Fanjing Mountain, and to know its distribution and diversity, carries on a study on this animal's external shape. The result shows that its bodily figure is large. Among the collected samples, the longest body length of this animal reaches 95 mm, with unique external form. Its marked feature is that there exists a striking light-coloured spot in the shape of "Y" at the juncture point between its back and its trail. Besides, the external structure of its mouthpart is not complicated, most patterns of whose labial teeth is I:5-5/5-5:I and I:5-5/4-4:I.
