During the mating season, males attract females by bellowing, slapping their snouts in the water, blowing water out of their noses, and making a variety of other noises. Among the larger males of a population, territorial clashes can lead to physical fighting between males especially if they are near the same size. Such clashes can be brutal affairs and can end in mortality but typically end with victor and loser still alive, the latter withdrawing into deep waters. [104] [105] Once a female has been attracted, the pair warble and rub the undersides of their jaws together. Compared to the tender behaviour of the female accepting the male, copulation is rather rough (even described as "rape"-like by Graham & Beard (1968)) in which the male often roars and pins the female underwater. [57] [105] Cott noted little detectable discrepancy in the mating habits of Nile crocodiles and American alligators. [10] In some regions, males have reportedly mated with several females, perhaps any female that enters his claimed territory, though in most regions annual monogamy appears to be most common in this species.

El cocodril caça en grup amb l'objectiu d'aconseguir preses més grans. Per això, els exemplars que són més petits o que estan per sota de la cadena de comandament són els primers que ataquen l'animal. Quan ja el tenen immobilitzat, és el cocodril més gran el que ataca de forma mortal, destrossant la presa i alimentant-se'n per després deixar als altres les restes.

A més, disposa d'un cos aplatat i robust en color verd olivera, fosc o bronze, amb un acolorit de groc a morat a la part del ventre. Acaba en una cua molt poderosa capaç de matar amb ella altres animals. Tot i això, el que més destaca d'aquest animal és el seu cap i, a dins, la boca composta per una dentadura d'entre 64 i 68 dents. Below is a cladogram showing the relationships of the major extant crocodile groups based on molecular studies, excluding separate extinct taxa:

Quan les cries han nascut, la femella es queda al seu costat per protegir-los ja que és molt gelosa amb els seus fills i fins i tot és capaç d'ajudar a néixer mossegant la closca però sense malmetre la vida que hi hagi a dins. Totes les cries les porta a l'aigua on, el primer any de vida, només uns quants sobreviuran i arribaran a adults. Les amenaces de l'espècie
