It's important to note that while Nile crocodiles occupy a vast region in Africa, their distributions within specific countries may vary and may not necessarily cover the entire area. Some areas can have more abundant populations and suitable habitats than others. Additionally, local population trends and conservation efforts can affect the presence and distribution of Nile crocodiles.
