两栖类主动吞食植物性食物的初步研究

A Preliminary Study on the Amphibians' choice of Vegetal Foods

两栖类主食昆虫,兼食其它动物性食物。在缺乏动物性食物的条件下,两栖类能主动吞食植物性食物。但不同的种类对植物性食物的消化程度有所不同。

Amphibians eat mainly insects and, sometimes, other animal foods. In the shortage of animal foods, amphibians will choose certain vegetal foods. However, the degree of digesting vegetal foods varies among different species of amphibians.
