crocodylidae
crocodylia
Reptilia
Incubation of 80-90 days
40-60 eggs
When they are small they feed on smaller aquatic invertebrates and insects. In adulthood, their prey is mainly large vertebrates, such as antelope, buffalo, zebra, wildebeest, etc. Fish and small vertebrates are also an important part of their diet.
About 45 years
Their incredible dimensions are impressive, as adults can measure 5-6 meters, and individuals measuring 7-8 meters have even been detected.
The sex of the Nile crocodile is determined by the temperature during the incubation period. If it is maintained in a range between 31,7-34,5ºC, males are born, if it is lower or higher, females are born. The female digs a nest in the sand where she buries her eggs and both parents care for the eggs during incubation.
The mother takes care of her babies until they reach two years old. During their first days of life the female carries them on her back or in her mouth with great care. This has given rise to the myth that Nile crocodiles eat their own young.
Despite its great adaptability, the species suffered a serious decline in the mid-90s due to abusive hunting, leading many populations to their disappearance. The trade in Nile crocodiles is currently regulated, many countries have implemented sustainable programs that include farms from which both the prized skin and meat are obtained.
The Nile crocodile helps maintain populations of predatory fish that could wipe out other small species the ecosystem depends on. On the other hand, they also consume dead animals that could contaminate the waters.
