对圈养的尼罗鳄的观察证实了早期关于父母照顾巢穴和幼鳄的报道。雄性和雌性在求爱后似乎形成了一对纽带，雄性与雌性一起保卫筑巢领土，很少离开巢穴，直到幼崽孵化的声音刺激她打开巢穴释放它们。雌性将未孵化的卵和活的幼鸟在她的颊囊中运输到水中，并建立一个托儿所，在那里保护幼鸟几个星期。实验涉及录音机播放的遇险呼叫，提供活的年轻人和鸡蛋的成年人，父母打开一个人工巢和发声和由此产生的成年人和年轻人之间的相互作用进行了描述。
Observations on captive Nile crocodiles, Crocodylus niloticus confirm earlier reports on parental care of nests and of young. Male and female appear to form a pair bond after courtship, the male defending nesting territory with the female rarely leaving the nest until the sounds of the young hatching stimulate her to open the nest to release them. The female transports unhatched eggs and live young in her buccal pouch to water and establishes a nursery where the young are defended for several weeks. Experiments involving playback of distress calls by tape recorder, offering of live young and eggs to the adults, the parent opening an artificial nest and vocalisations and resultant interactions between adults and young are described.
