Savannah Monitor
Varanus exanthematicus
On This Page▾
🌍 Overview
The savannah monitor is a medium-to-large monitor lizard native to the sub-Saharan African savanna and semi-arid grasslands. In the wild they are highly active, covering considerable distances in search of prey and aestivating in burrows during the dry season. Despite a reputation for being tameable, savannah monitors in captivity frequently suffer from obesity and shortened lifespans due to improper high-fat diets.

📜 History
The French naturalist Louis Augustin Guillaume Bosc named the species Lacerta exanthematica in 1792. Two centuries later it had become one of the highest volume reptiles in the world pet trade, drawn almost entirely from West Africa: CITES records show Ghana exporting 235,903 live animals between 2000 and 2010, Togo 188,110 and Benin 72,964. The United States absorbed most of that supply, importing 325,480 live savannah monitors over the same decade, an average of about 30,574 a year. Declared worldwide exports of skins and other products across that period came to 37,506, a fraction of the trade in living animals.

🤓 Did You Know?
Savannah monitors are built for digging. In the wild they may create burrows several feet deep to escape the African heat. A deep substrate is one of the most important enrichment features you can give them!
