Cocodril, putxinel-lis per al bany

Per descomptat, també altres animals salvatges poden acabar amb la vida d'aquests cocodrils, i fins i tot ells mateixos per la lluita pel poder dels grups, ja que només els més forts són els que es reprodueixen i s'alimenten abans. Els altres queden en un segon o tercer pla, a costa dels altres més grans i forts. Curiositats del cocodril del Nil Grabham, G. W. (1909). "A Crocodile's Nest". Nature. 80 (2056): 96.

The Old French word was later refashioned after the Latin and Greek… At the time of hatching, the young start calling within the eggs. They have an egg-tooth at the tip of their snouts, which is developed from the skin, and that helps them pierce out of the shell. Hearing the calls, the female usually excavates the nest and sometimes takes the unhatched eggs in her mouth, slowly rolling the eggs to help the process. The young is usually carried to the water in the mouth. She would then introduce her hatchlings to the water and even feed them. [81] The mother would then take care of her young for over a year before the next mating season. In the absence of the mother crocodile, the father would act in her place to take care of the young. [82] However, even with a sophisticated parental nurturing, young crocodiles have a very high mortality rate due to their vulnerability to predation. [83] A group of hatchlings is called a pod or crèche and may be protected for months. [78] Cognition Rochford, Michael R.; etal. (30 April 2016).

The most common method is to measure lamellar growth rings in bones and teeth—each ring corresponds to a change in growth rate which typically occurs once a year between dry and wet seasons. [68] Bearing these inaccuracies in mind, it can be safely said that all crocodile species have an average lifespan of at least 30–40 years, and in the case of larger species an average of 60–70 years. The oldest crocodiles appear to be the largest species. C. porosus is estimated to live around 70 years on average, with limited evidence of some individuals exceeding 100 years. [69] Chemoreception in crocodiles is especially interesting because they hunt in both terrestrial and aquatic surroundings. Crocodiles have only one olfactory chamber and the vomeronasal organ is absent in the adults [40] indicating all olfactory perception is limited to the olfactory system. Behavioural and olfactometer experiments indicate that crocodiles detect both air-borne and water-soluble chemicals and use their olfactory system for hunting. When above water, crocodiles enhance their ability to detect volatile odorants by gular pumping, a rhythmic movement of the floor of the pharynx. [41] [42] Crocodiles close their nostrils when submerged, so olfaction underwater is unlikely. Underwater food detection is presumably gustatory and tactile.

Alternatively, some morphological studies have recovered Mecistops as a basal member of Crocodylinae, more closely related to Crocodylus than to Osteolaemus and the other members of Osteolaeminae, [90] [99] as shown in the cladogram below.
