本文报道了巴西东南沿海浅水水域尖吻石斑鱼(Comb Grouper Mycteroperca Acutirostris)对死亡或疾病伪装的野外观察，并对这一独特的捕食行为进行了评论，这一行为类似于以前在非洲记录的一种慈鱼的死亡伪装。一只在黄昏捕食幼鱼的个体在连续五次捕食过程中成功地采用了这种不寻常的摄食策略。老化的比赛。没有观察到其他尖吻姬鼠假装死亡，这种行为似乎是跟踪策略的一种修改。
This paper reports field observations on dying or illness feigning by the Comb Grouper Mycteroperca acutirostris in shallow waters of the southeastern Brazil's coast, and comments on this unique hunting behavior, similar to death feigning previously recorded for a cichlid species in Africa. An individual preying on young fishes at dusk successfully employed this unusual feeding strategy during five sequential for. aging bouts. No other M. acutirostris individual was observed feigning dying, a behavior that seems to be a modification of the stalking tactic.
