Species – Crocodylus niloticus
The Nile crocodile is widespread throughout sub-Saharan Africa and Madagascar. It inhabits rivers, lakes, swamps, and reservoirs, preferring freshwater but can also tolerate brackish lagoons.
Lifespan in the wild – up to 70 years; in captivity – over 80 years. Males weigh between 400–750 kg, females – 200–400 kg. Males reach 4.5–5.5 m in length (sometimes up to 6 m); females – 2.5–3.5 m. Nile crocodiles are semi-aquatic predators that spend most of their time basking or hunting near water. They are social animals and often gather in groups during feeding or nesting. Females lay 25–80 eggs in sand nests, guarding them for about 80–90 days. Hatchlings call from inside the eggs to alert the mother, who helps them reach the water. Carnivorous. Feeds on fish, birds, mammals, and amphibians. Juveniles eat insects and small invertebrates. Adults hunt by ambush using powerful jaws.
Modern crocodiles descend from ancient archosaurs that lived about 250 million years ago. Crocodylus niloticus evolved around 3–5 million years ago in Africa. In ancient Egypt, the Nile crocodile was revered and associated with the god Sobek — symbolising strength and fertility.
Today, it remains a powerful cultural symbol and frequently appears in films and documentaries about African wildlife.
According to the IUCN, the Nile crocodile is listed as Least Concern, though local populations face threats from habitat destruction and illegal hunting.
