How Many Species of Venomous Lizards Exist

There are several species of venomous lizards, but how many exactly? According to recent research, there are at least 10 species of venomous lizards that exist.

Some of the most well-known species of venomous lizards include the Gila monster and the Mexican beaded lizard. These species are found in the deserts of North and Central America.

The Gila monster, for example, is a large lizard that can grow up to 3 feet in length and is known for its distinctive pink and black markings.

You might be surprised to learn that some lizards are venomous, not just snakes. There are several species of venomous lizards, and they're found all over the world.

Some of the most poisonous lizards are monitor lizards, which have over 80 species. Among them, Dumeril's monitor and the lace monitor are worth investigating for their venomousness.

These monitor lizards have distinctive markings that might serve as warning coloration, indicating the presence of venom. Hatchlings of Dumeril's monitor have an orange head and a white-banded black body, which is different from the adults.

The lace monitor's venom production is still a topic of debate, and Dumeril's monitor has never been tested for venom. However, since they mostly eat invertebrates and not live prey, it's possible that their venom is used for defense, not hunting.

The Gila Monster, native to the southwestern U.S., is another venomous lizard. Its venom can cause extreme pain, swelling, and breathing difficulties in humans.

Monitor lizards are not just any ordinary lizards, they pack a toxic punch. Some species of monitor lizards secrete mild venom that can cause swelling and blood thinning.

The Lace Monitor, found in Australia, is one such example. Its bite is painful but rarely dangerous to humans. The Asian Water Monitor, on the other hand, carries venom in its glands, which can cause severe pain, infection, and tissue damage.

Among the nearly 80 species of monitor lizards, there are two species with conspicuous markings that deserve investigation as possible cases of warning colouration. These are Dumeril's monitor and the Lace Monitor.
