1.1 What is a Monitor Lizard?
A monitor lizard is any lizard belonging to the Varanidae family, encompassing the Varanus genus. These reptiles are known for their intelligence, active nature, and varied appearances. Similar to snakes, these lizards often have long, forked tongues.
Monitor lizards first emerged approximately 15 million years ago during the Miocene epoch. Fossil evidence indicates that some extinct species reached enormous sizes, with the largest reaching lengths of up to 7 meters and weights of 600 kilograms.
While ancient monitors were giants, modern species vary significantly in size. The smallest, such as some dwarf monitors, reach only 20 centimeters in length, while the Komodo dragon (Varanus komodoensis) can grow to 3 meters long. Most monitors average between 1 and 3 meters.
Coloration varies depending on habitat. Desert dwellers often display orange or yellow hues, while those living near water or in forests are typically dark-colored. Some species feature spots, speckles, or bands depending on age and species.
1.2 Different Types of Monitor Lizards as Pets
- Ackie Monitor (Varanus acanthurus): A smaller species, reaching about 2 feet in length, known for its relatively docile temperament and ease of care. Requires a 4x2x2 foot enclosure.
- Savannah Monitor (Varanus exanthematicus): A larger species, growing up to 5 feet long, requiring a significant enclosure. Can be more challenging to handle due to size. Requires a 6x3x3 foot enclosure.
- Nile Monitor (Varanus niloticus): A large and intelligent lizard, reaching up to 7 feet in length. Needs a very large enclosure and is not recommended for beginners due to its powerful bite and potentially aggressive nature. Requires an 8x4x4 foot enclosure with a large water area.
- Dumeril’s Monitor (Varanus dumerilii): A medium sized species, that reaches approximately 4 feet in length. These monitors can be found in Southeast Asia and are popular due to their docile temperament. Requires a 6x3x3 foot enclosure.
