Nile Crocodile

Crocodylus niloticus

The Nile crocodile is Africa's largest reptile and one of the most feared animals on the continent. Growing up to six meters long and weighing over a tonne, these ancient predators have been perfecting their ambush hunting technique for over 200 million years. They are essentially living dinosaurs, and watching one explode from the water to seize a wildebeest mid-crossing is among the most violent and awe-inspiring moments on any African safari. Crocodiles are found in rivers, lakes, and wetlands across sub-Saharan Africa, but the most spectacular viewing happens during the Great Migration's river crossings. At the Mara and Grumeti rivers, massive crocs lie in wait for the annual flood of wildebeest, launching attacks with terrifying speed and power. Outside of migration season, crocodiles are a constant presence on boat safaris in Botswana's Chobe River, the Zambezi, and the waterways of the Okavango Delta. They bask on riverbanks with their mouths open (a thermoregulation behavior, not a threat display) and slip silently into the water when boats approach. Nile crocodiles are patient predators. They can go months between meals and will wait motionless at a riverbank crossing point for weeks. They are also surprisingly attentive parents. Females guard their nest for three months and gently carry newly hatched babies to the water in their jaws. Despite their fearsome reputation, crocodiles face real threats from habitat loss and illegal hunting for their skin. Healthy crocodile populations indicate a healthy river ecosystem.
