African Lion Quick Facts
What Is the Nile Monitor?
The Nile Monitor (Varanus niloticus) is a large semi-aquatic monitor lizard with powerful swimming and climbing ability, associated with water and changing food resources.
Habitat
- Woodland, dry savanna, scrub and evergreen thickets
- Swamps, mangroves and lake and river margins and wetland edges
Occurs in waterside mosaics, not open dune fields.
Diet
Broad and opportunistic: fish, amphibians, reptiles, birds, eggs, rodents, insects, crustaceans, molluscs and carrion. Strong posterior teeth help process hard-shelled prey such as molluscs.
Behaviour
Usually solitary, diurnal and active forager. Powerful swimmer and capable climber that often flees toward water when threatened. When cornered it may hiss, inflate, lash its tail, bite and release a foul cloacal secretion. Individuals can make substantial local movements within home ranges. Generally solitary outside reproduction.
Where to See Nile Monitors in Tanzania
Nyerere, Lake Manyara and other verified Tanzanian aquatic and wetland locations. Good opportunity in suitable waterside habitat, but sightings are variable and never guaranteed. Photography best for basking, swimming, climbing and waterside tongue-flicking.
