Husbandry requirements
Savannah monitor — origin: Sub-Saharan Africa — savannahs.
Terrarium temperature gradient
Night min22 °C
Cool side26–26 °C
Warm side28–32 °C
Basking spot45–55 °C
Very hot basking surface (desert basker); measure the surface temperature
Enclosure (adult)
240 × 120 × 60 cm
Very large terrarium with deep substrate
Substrate at least 30–60 cm deep to allow digging and to hold a burrow
Humidity
40–60 %
Higher humidity in the burrow; hydrates the animal
Substrate
Deep soil/sand mix (holds the burrow)
UVB
Recommended
ESSENTIAL — strong UVB (Ferguson zone 3–4)
Water source
Always available
Large tub for bathing
Origin
Varanidae
Sub-Saharan Africa — savannahs
02
Feeding & health
Diet
Carnivore/insectivore — Mostly invertebrates (roaches, locusts, snails); occasional eggs and rodents
VERY prone to obesity / hepatic lipidosis — avoid an excess of fatty rodents
Breeding
Oviparous
Clutch 10–50 eggs/young. Digs a nest to lay eggs
Health watch points
- Obesity / hepatic lipidosis (overfeeding of rodents — a major problem)
- MBD (metabolic bone disease)
- Parasites (wild-caught)
- Thermal burns
- Respiratory infections

Frequently asked questions
Answers to the most common questions about keeping the savannah monitor.
How large does an adult savannah monitor get?▾
It is a massive, stocky lizard measuring 90 to 130 cm in total length as an adult. It is its heavy build, more than its length, that explains the considerable space it needs.
What enclosure dimensions should you provide?▾
Plan on at least 240 × 120 × 60 cm for an adult, with a substrate layer of 30 to 60 cm so it can dig and maintain a burrow. This is a burrowing species: floor area and substrate depth take priority over height.
What temperatures should you offer it?▾
It needs a very hot basking spot, between 45 and 55 °C in surface temperature, a warm zone of 28 to 32 °C and a cool side around 26 °C, with a nighttime drop falling to at least 22 °C. Be sure to measure the surface temperature of the basking site, as this desert monitor seeks intense, localised heat.
Does it need UVB?▾
Yes, UVB is essential and must be powerful (Ferguson zone 3 to 4). It is a diurnal lizard whose calcium metabolism depends directly on high-performance UV lighting.
What does the savannah monitor really eat?▾
Contrary to a widespread belief, it is not a rodent eater: in the wild it mainly consumes invertebrates (cockroaches, locusts, snails), and its captive diet should remain predominantly insectivorous, with only occasional eggs or rodents. An excess of fatty prey such as rodents causes obesity and hepatic lipidosis.
Why is obesity such a danger in this species?▾
Overfeeding on fatty rodents is the species' major problem: it leads to hepatic lipidosis, that is a fatty degeneration of the liver that is often fatal. A monitor properly fed on insects stays active, whereas an obese monitor becomes lethargic and sees its life expectancy collapse.
How long does a savannah monitor live?▾
Generally 10 to 15 years, but poor husbandry often reduces that figure, while a well-kept animal can approach 20 years. Longevity depends directly on diet and on preventing obesity.
Is it a good reptile to start with?▾
No, it is an advanced-level species. Its power, its need for a very large volume, deep substrate and powerful UVB, along with its strong susceptibility to obesity, make it a demanding animal, all the more so as many specimens are wild-caught.
Does it need a tub to bathe in?▾
Yes, provide a large tub in which it can fully submerge. It enjoys bathing, which also contributes to its hydration and to the proper progress of its sheds.
Can it be tamed and handled?▾
It can become relatively docile with regular work, but it remains a powerful animal, and juveniles are often defensive. As many individuals come from wild capture, handling requires patience and caution.
What humidity level should you maintain?▾
An ambient humidity of 40 to 60 % is suitable, with a more humid burrow at the bottom of the substrate. This buried humid zone helps the animal to hydrate and to regulate its sheds.
What health problems should you watch for?▾
Beyond obesity and hepatic lipidosis, watch for metabolic bone disease, parasites (common in wild-caught animals), thermal burns linked to heating elements and respiratory infections. Monitoring by an exotics vet is recommended.
