摘　　要：2022年5月22日,江西官山国家级自然保护区布设的红外相机记录到1只食蟹獴捕食中华蟾蜍一例,该獴进食后出现倒地、侧卧和仰卧等痉挛动作,经过查看红外相机记录的267次行为并进行比对,认为该獴出现痉挛动作与取食中华蟾蜍的相关显著,符合一些哺乳动物的蟾蜍中毒症状。经查阅相关文献,有獴属动物捕食其他种类蟾蜍的记录。经分析认为,食蟹獴能够捕食中华蟾蜍的主要原因在于:一是食蟹獴把蟾蜍按在地面上翻滚摩擦,擦除了一些体表受刺激时分泌的毒性浆液;二是避开了含毒量高的头部和背部的皮肤,仅吃肌肉和内脏。On May 22,2022,an infrared camera in Jiangxi Guanshan National Nature Reserve recorded a case of a crab-eating mongoose preying on a Chinese toad.The mongoose appeared convulsive movements after feeding,such as falling down,lying on its side and lying on its back.Through the comparison of 267 behaviors recorded by the infrared camera,it was concluded that the convulsive movements of the mongoose were significantly correlated with feeding on a Chinese toad.Consistent with the symptoms of toad poisoning in some mammals.There have been records of mongoose preying on other species of toads.According to the analysis,the main reason that crab-eating mongoose can prey on Chinese toad is:first,crab-eating mongoose toad press on the ground rolling friction,wipe away some of the body surface when stimulated secreted toxic slurry.The other is to avoid the toxic head and back of the skin,only eat muscle and internal organs.Third,the body of crab-eating mongoose has certain tolerance and detoxification mechanism.
