摘要

摘要在蜘蛛中，食腐似乎是一种保守但灵活的特征。虽然在圈养环境下的食腐行为有很好的记录，但在野外的观察却很少见到。在2021年9月6日的一次道路生态调查中，我观察到一只成年雄性沙漠金色狼蛛(Aphonopelma chaldes)正在吞食一条被公路杀死的西部钻石背响尾蛇(Crotalus atrox)幼崽。狼蛛对我的缓慢接近没有反应，我观察到它的螯肢刺进了蛇的软组织。对兽角兽食腐的观察是相当罕见的，这可能是第一次报道狼蛛在爬行类动物的尸体上食腐。

Scavenging of Western Diamond-Backed Rattlesnake (Crotalus atrox) by Desert Blonde Tarantula (Aphonopelma chalcodes) in Arizona

Abstract. Scavenging appears to be a conserved but flexible characteristic among spiders. Although scavenging behavior is well documented in captivity, observations in the wild are rarely witnessed. During a road ecology survey on 6 September 2021, I observed an adult male desert blonde tarantula (Aphonopelma chalcodes) scavenging upon a roadkilled neonate western diamond-backed rattlesnake (Crotalus atrox). The tarantula did not react defensively to my slow approach, and I observed its chelicerae working into the snake's soft tissue. Observations of theraphosids scavenging are quite rare, and this may be the first reported instance of tarantula scavenging upon a reptilian carcass.
