The diet of wild Nile crocodiles (Crocodylus niloticus) is difficult to assess because they are cryptic and nocturnal predators that are extremely sensitive to disturbance by observers, and stomach content analysis is challenging, especially in large specimens. Stable light isotope analysis provides a means of assessing their diet, but diet-to-tissue discrimination factors have yet to be established for the species.

尼罗鳄 (Crocodylus niloticus) 同位素饮食对组织区分因素的个体发育依赖性

野生尼罗鳄 ( Crocodylus niloticus )的饮食难以评估，因为它们是神秘的夜间捕食者，对观察者的干扰极为敏感，胃内容物分析具有挑战性，尤其是在大型标本中。稳定的轻同位素分析提供了一种评估其饮食的方法，但尚未确定该物种的饮食对组织的区分因素。
