摘要
鳄蜥(Shinisauruscrocodilurus)是濒危的孑遗物种,生存遭受多方威胁。除人为猎杀和生境受到破坏之外,天敌也是其致命的威胁之一,但目前关于其被天敌捕食的研究非常匮乏。本文报道了绿瘦蛇(Ahaetullaprasina)捕食鳄蜥的现象,以全事件记录法观察了这一行为过程。鳄蜥面对的被捕食风险可能较广。除蛇外,鳄蜥的天敌也可能是鸟类等动物。在饲养繁育中,要注意加强防范举措,以免鳄蜥被天敌侵害。
The crocodile lizard(Shinisaurus crocodilurus) is an endangered relict species, and has been threatened by many factors. In addition to human hunting and habitat destruction, natural enemies are also one of their deadly threats. However, the current research on its predation by natural enemies is very scarce. This paper reported the phenomenon of Ahaetulla prasina preying on the crocodile lizard. We observed this preying behavior by full event recording method. The crocodile lizard probably faced a higher risk of being prey. Besides snakes, its natural enemies may also be animals such as birds. During the procedure of raising and breeding, we must pay attention to strengthen prevention measures to prevent the crocodile lizard from being invaded by natural enemies.
