També se sap que aquest rèptil és capaç d'alentir el seu metabolisme quan no hi ha aliment del qual menjar, podent, en un any, ingerir menjar només cinc o sis vegades sense perjudicar-ne el cos. Nile crocodiles usually dive for only a few minutes at a time, but can swim under water up to 30 minutes if threatened. If they remain fully inactive, they can hold their breath for up to 2 hours (which, as aforementioned, is due to the high levels of lactic acid in their blood). [19] They have a rich vocal range and good hearing. Nile crocodiles normally crawl along on their bellies, but they can also "high walk" with their trunks raised above the ground. Smaller specimens can gallop, and even larger individuals are capable of occasional, surprising bursts of speed, briefly reaching up to 14km/h (8.7mph). [10] [88] They can swim much faster, moving their bodies and tails in a sinuous fashion, and they can sustain this form of movement much longer than on land, with a maximum known swimming speed of 30 to 35km/h (19 to 22mph), more than three times faster than any human.

Conservation organizations have determined that the main threats to Nile crocodiles, in turn, are loss of habitat, pollution, hunting, and human activities such as accidental entanglement in fishing nets. [25] Though the Nile crocodile has been hunted since ancient times, [123] the advent of the readily available firearm made it much easier to kill these potentially dangerous reptiles. [9] The species began to be hunted on a much larger scale from the 1940s to the 1960s, primarily for high-quality leather, although also for meat with its purported curative properties. The population was severely depleted, and the species faced extinction. National laws, and international trade regulations have resulted in a resurgence in many areas, and the species as a whole is no longer wholly threatened with extinction. The status of Nile crocodiles was variable based on the regional prosperity and extent of conserved wetlands by the 1970s. [124] However, as is the case for many large animal species whether they are protected or not, persecution and poaching have continued apace and between the 1950s and 1980s, an estimated 3 million Nile crocodiles were slaughtered by humans for the leather trade. [22] In Lake Sibaya, South Africa, it was determined that in the 21st century, persecution continues as the direct cause for the inability of Nile crocodiles to recover after the leather trade last century. [125] Recovery for the species appears quite gradual and few areas have recovered to bear crocodile populations, i.e. largely insufficient to produce sustainable populations of young crocodiles, on par with times prior to the peak of leather trading. [102] Crocodile 'protection programs' are artificial environments where crocodiles exist safely and without the threat of extermination from hunters. [64] Large adults in captivity, Djerba, Tunisia Nile crocodiles in captivity, Israel Isolated populations also exist in Madagascar, which were supposed to have likely colonized the island very recently, after the extinction of the endemic crocodile Voay within the last 2000 years . [68] [69] However in 2022 a skull of Crocodylus from Madagascar was found to be around 7,500 years old based on radiocarbon dating, suggesting that the extinction of Voay post-dates the arrival of Nile crocodiles on Madagascar. [70] Nile Crocodiles occur in the western and southern parts of Madagascar from Sambirano to Tôlanaro. They have been spotted in Zanzibar and the Comoros in modern times, but occur very rarely.
