[h=2]Biology[/h] The genus
Varanus is considered unique among animals in that its members are relatively morphologically conservative and yet show a range in size that is equivalent to a mouse and an elephant.[SUP]

Most monitor lizards are carnivorous.[SUP]
[5][/SUP] Monitor lizards are infamous for their active nature, maintaining large territories and employing active pursuit hunting techniques that are reminiscent of similar sized mammals.[SUP]
[5][/SUP] The active nature of monitor lizards led to numerous studies on the metabolic capacities of these lizards. The general consensus is that monitor lizards have the highest standard metabolic rates of all
extant reptiles [SUP]

Monitor lizards have a high aerobic scope[SUP]
[6][/SUP][SUP]
[7][/SUP] that is afforded, in part, by their heart anatomy. Whereas most reptiles are considered to have three chambered hearts, the hearts of monitor lizards as with those of
boas and
pythons have a well developed
ventricular septum that completely separates the
pulmonary and
systemic sides of the circulatory system during
systole.[SUP]
[8][/SUP] This allows monitor lizards to create mammalian-equivalent pressure differentials between the pulmonary and systemic circuits,[SUP]
[8][/SUP] which in turn ensures that oxygenated blood is quickly distributed to the body without also flooding the lungs with high pressure blood.
Anatomical and molecular studies indicate that all varanids (and possibly all lizards) are partially
venomous.[SUP]
