摘　　要：鳄蜥(Shinisaurus crocodilurus)主要捕食部分昆虫、蜘蛛、蚯蚓、小型蛙类和小鱼等,但尚未见报道鳄蜥捕食其他相对较大的动物。本文报道了鳄蜥捕食变色树蜥(Calotesversicolor)和翠青蛇(Cyclophiopsmajor)的现象,以全事件记录法观察分析了鳄蜥猎捕这两种爬行动物的行为过程。这次新发现说明鳄蜥食谱较广,具有捕食蜥蜴等个体偏大动物的能力。因此,我们建议在饲养繁育中投喂更多类型的食物以避免营养不良。The crocodile lizard(Shinisaurus crocodilurus)mainly preys on small animals including insects,spiders,earthworms,frogs and fish,but whether it can prey on relatively large animals like other reptiles is unknown yet.Here we reported for the first time that crocodile lizards preyed on an oriental garden lizard(Calotes versicolor)and a greater green snake(Cyclophiops major).The predation process was observed and analyzed using all occurrence sampling.This discovery indicates that the crocodile lizard has a wide diet,and is capable of preying on large animals like lizards.Therefore,we recommend that a diversity of foods should be provided to crocodile lizards in captivity to avoid malnutrition.
