Do you want to learn about the Monitor Lizard?

Monitor lizards fall under the Varanus genus. Varanidae is the only genus still living in the family, and this animal is known to have 80 different species.

In addition to having well-developed limbs, they have long necks, solid claws, and tails.


There are several terrestrial species of monitor lizards. But there are also semiaquatic and arboreal species. However, depending on their habitat, some monitor lizards are herbivorous.

Distribution Of Monitor Lizards Across The World
These animals inhabit a considerable portion of the planet, from Africa down to the Indian subcontinent, China, and even the Philippines. According to specifications, South Florida is home to the Nile monitor.

Diet of Monitor Lizards

The majority of monitor lizards eat meat. Insects, crustaceans, myriapods, fish, amphibians, reptiles, birds, and mammals are just a few prey items they consume. Some species start eating invertebrates as juveniles before feeding on vertebrates as adults.

They can live alone or in groups of up to twenty or twenty-five other monitor lizards in habitats with few water supplies.

Some monitor lizards eat only plants, and their habitat significantly impacts their eating.

Territories of monitor lizards are sizable. They adopt active hunting methods and prey on mammals of comparable size. Researchers have conducted numerous investigations on these lizards’ metabolic capacity due to their busy habits.

Of all living reptiles, researchers think monitor lizards have the most outstanding standard metabolic rates.

Monitor Lizard Anatomy And Habitat

monitor lizard facts

The hearts of monitor lizards have a well-developed ventricular septum. This septum entirely divides the pulmonary and systemic sides of the circulatory system, in contrast to the hearts of most reptiles, which have three chambers. This gives them a sizeable aerobic range.

Their capacity to produce pressure differences between the pulmonary and systemic circuits is equal to those in mammals.
A monitor lizard’s venom is complicated and varied. This is due to the variety of ecological habitats that monitor lizards occupy.

From 7 to 38 eggs are laid by monitor lizards. Frequently, they bury their eggs in the ground or tuck them away in a hollow tree stump.
The sole surviving member of the Varanidae family is the Monitor Lizard species Varanus.

Origin And Etymology

Because varanids tend to stand on their two hind legs and “monitoring,” the term “monitor lizard” may have been adopted to describe them. Their practice of “warning individuals of the approach of venomous creatures” may have also been a factor in its adoption.

In Austronesia, where they are widespread, varanids go by various names. They can also go by the names “biawak” (of the Malay variety), “bayawak” (of the Filipino kind), “binjawak,” “minjawak,” or “nyambik” (Javanese).

Their name is “hangkok” in South Asia. “Mwpou” is the Meitei word, and “umbu” is the Marathi word.
They have numerous names throughout West Africa. “Awonriwon” or “àlégbà” are its names in Yoruba.

How intelligent are Monitor Lizards?

Some monitor species can count. They can count to six, according to studies. When foraging, they also work together. One of the monitors lures the mother crocodile away when they attempt to feast on her eggs, and the others continue to eat the eggs. The decoy returns to consume the eggs once the pack has finished its meal.


It is possible to keep monitoring lizards as pets. If you’re “weird” enough to desire a pet lizard, that is. The savannah monitor is one of the species that are maintained most frequently. This is due to its diminutive size and its composure under routine handling.

The Nile monitors, however, are housed in captivity. South India forbids the capture or slaughter of monitor lizards, even though some are held in captivity. The Protected Species Act forbids it.

Both the monitors and their leathers are exploitable.

Some Indians, Filipinos, Australians, and Africans eat their meat. That is, people use them as an additional source of meat.

Despite not being an endangered species, monitors’ population is declining, which is cause for concern. All but five species of monitor lizards appear in the Convention on International Trade in Endangered Species of Wild Fauna and Flora. They broadly refer to ” species that are not yet in danger of going extinct but could do so if trade in these species is not strictly regulated to prevent use that is incompatible with their survival in the wild.”

The following species are listed in CITES: V. bengalensis, V. flavescens, V. griseus, V. komodoensis, and V. nebulosus. Any trading in the species on a global scale is now prohibited. Except for Bhutan, Nepal, India, Pakistan, and Bangladesh, every nation in the yellow monitor’s habitat has laws protecting the species (V. flavescens).

Appearance And Physical Features of Monitor Lizard

It is acceptable to remark that reptiles are not the most aesthetically pleasing animals in terms of appearance and physical characteristics.

This does not imply that these species are unsightly, though. Even as animals, they do not meet the requirements for aesthetic appeal. In other words, they look ugly. But now that you know better, shouldn’t it dissuade you from having a predatory lizard as a pet?

However, the yellow monitor’s color might appeal to someone on an aesthetic level.
That will be all about the Monitors.

Reptiles are fascinating, but Monitor Lizards are up the fold! Firstly, they are reptiles; then, they can stand on their hind legs and monitor.

They can count, are quite a cooperative group, and you can keep them as pets. Humans can exploit them for their leather and use them to make musical instruments, clothes, bags, shoes, and whatnot.

Even more interesting is that people can eat them! Although only by a quarter of the population of people on Earth. Do not forget; they are not all fun; they are carnivores and may be violent, as is their nature.
