They are native to Africa, Asia, and Oceania, and one species is also found in the Americas as an invasive species. [1] About 80 species are recognized. Monitor lizards have long necks, powerful tails and claws, and well
Using one of these definitions leads to the inclusion of the earless monitor lizard (L. borneensis) in the family Varanidae. Lee (1997) created a different definition of the Varanidae, defining them as the clade containing Varanus and all taxa more closely related to Varanus than to Lanthanotus ; [ 6 ] [ 7 ] this definition explicitly excludes ...
This is a list of the deadliest animals to humans worldwide, measured by the number of humans killed per year. Different lists have varying criteria and definitions, so lists from different sources disagree and can be contentious. This article contains a compilation of lists from several reliable sources.
The largest is the perentie (V. giganteus), which can grow over 2.5 m (8.2 ft) in length. Not all goannas are so large; pygmy goannas may be smaller than the arm of an adult human. The smallest of these, the short-tailed monitor (V. brevicauda), reaches only 20 cm (8 in) in length. They survive on smaller prey, such as insects and mice.
Megalania (Varanus priscus) is an extinct species of giant monitor lizard, [1] part of the megafaunal assemblage that inhabited Australia during the Pleistocene.It is the largest terrestrial lizard known to have existed, but the fragmentary nature of known remains make estimates highly uncertain.
Scientists say they have recovered the oldest known Homo sapiens DNA from human remains found in Europe, and the information is helping to reveal our species’ shared history with Neanderthals.

While most reptiles are considered to have three-chambered hearts, the hearts of true monitors – as with those of other monitors – have a well developed ventricular septum that completely separates the pulmonary and systemic sides of the circulatory system during systole.
