Fast Facts

General Description

Black-Throated Monitor Lizards are giants by nature. They have short but strong muscular legs, giant claws, sharp teeth, and long fat tails. Like all other reptiles, they have rough and thick skin for protection against large predators and prey that fight back. These Monitors are generally calm tempered reptiles, but they hiss when they sense a threat and inflate their bodies to make themselves seem more bulky and significant. They also whack predators with their robust and powerful tails. Sometimes they will even try to bite if the predator gets close. They have long, forked tongues (like snakes) to sense odors. They prefer to eat live prey in the wild, but they mostly eat dead animals such as mice, rats, other rodents, and even smaller chickens in captivity. Since these Black Throat monitors are not social creatures, they might turn aggressive if not trained or handled regularly in captivity. These giant Monitors love to spend their days climbing trees or digging to stay calm or take a nap.

Sexual Dimorphism:

Male Monitors will grow much faster than female Monitors.

Specifications of species:

The Black-throated Monitor is a member of the Varanidae family of lizards. Due to recent changes and conflicting use of common names, there is some confusion about this species’ actual taxonomic classification. It was thought that Black Throat Monitors are sub-species of white-throat monitors. Now, black-necked monitors and white-necked monitors are considered different species


The black throat monitor is territorial. This Monitor lives in various dry habitats, including prairies, steppes, and savannas, but is missing from rainforests, deserts, and dense bushes.


Restricted eaters plus obligate carnivores. They will eat anything they can catch. They eat prey in captivity, such as rats, lizards, mice, mollusks (freshwater), snakes, small birds, large roaches, fish, eggs, and crustaceans.

Activity and behavior

Black-throated Monitor social behavior

The Hunting area for a male is approximately 7.5 square miles from home, while for females, it is 2.5 square miles. Their range reduces up to many folds in the dry season.

Reproductive behavior of Black Throat Monitors

Their breeding season starts in mid-August and ends at the start of October. Females prefer to do mating on trees. They climb a tree and wait for the counter partner to come.

When the males get the female, they will stay together for 3-4 days, after which the female will lay 1-2 egg clusters/clutches and put them in burrows.

Black Monitors Offspring

The incubation period of the Black Monitors egg is 35-37 days. They deposit their eggs at different sites. Some Monitor females seem to prefer digging their nests into almost the rock hard bottoms of the ant or termite mounds.

Nature creates an extraordinary phenomenon to save their eggs for the sustainability of this species. Naturally, the termites rebuild their mounds around the eggs in the wild to retain the humidity essential for their existence, thus protecting the Black Monitor eggs encased inside their mounds and also provide them with the optimal moisture they need.

These Monitors are adapted to bury their eggs in moist soil that retains moisture. When variations occur in regular moisture or environment, these eggs can take a year to hatch!

Monitors Conservation Status

  • Monitors are at considerable risk because of their requirements for large areas of their optimum habitat.
  • They are considered somewhat endangered because of excessive hunting and killing in the past for food.
    Their leathery coat is also costly, so they also become the victim of the illegal leather trade.
  • Local people also kill them due to fear or for some spiritual reasons
  • Black Monitors body organs and their skin is also used in some local and traditional medicine.
