Types of Lizards
Boyd's Rainforest Dragon
Lizards are Reptiles, or members of the class Reptilia, and inhabit all of the continents apart
from Antarctica. Lizards live in diverse environments and are the most geographically
widespread of the reptiles. That makes them the largest group of reptiles with about 5000
species. They have walked the earth for some 200 million years.

Reptiles have the following physical features: they have vertebrate, lungs, and scales or plates.
They are cold-blooded, getting all of their heating from the environment (the sun) which can be
deadly during cold spells. What could be good about that? Well, this allows the reptiles to eat
much less than a mammal of the same weight might. In the desert, for example, this might be
useful in terms of competing for food. Also, since they don't need so much energy from food to
heat themselves they can spend more time basking and taking in the sites.
Most lizards are four-legged, but some have only two legs and even a few are leg-less. Lizards
size ranges from 2 in to 10 ft in length. There are 2 species that are venomous, the Gila
Monster and the Mexican Beaded Lizard.

Collared Lizard
Some lizards change colors very quickly to match their environment, like the Chameleon. Their
colors are also affected by the sun. Often, when basking in the sun, the colors of a lizard's skin
can become bright and vibrant like the Collared Lizard. A cold lizard may be dark and colorless.
Distinct colors, aside from simply being interesting, like having a blue tongue, a bright red
dewlap, or yellow spots, may help lizards identify each other and even communicate. Lizards
have very keen eyesite and they also use body language posturing and gestures such as head-
bobbing to communicate with each other.
You may also notice that the Collared Lizard above is shedding a layer of old skin. The skin or
scales of a lizard is made up of keatin. This substance is also what human fingernails are made
of. Collared lizards are known to be aggresive and they eat other species of lizards.

Common Iguana
Unfortunately for lizards, life on the earth populated with humans is not all about good times.
Central Americans do like to eat the iguanas and think they taste good, calling them "tree
chicken". In Central America, the black iguanas are called garrobos, and the green iguanas are
called iguanas, so you might find "sopa de garrobo" or "iguana soup" on some menus.
Charbroiled tail of iguana can also be found. The common method of hunting is with a
slingshot. Freshly killed prey is often held up for display alongside the highway by the hunters,
in order to entice buyers. Another lizard, the Uromastyx or Spiny-tailed lizard, is commonly
eaten in many countries from Northern Africa through the Middle East and in India.
Common Iguanas are not bad swimmers. When attacked, an iguana may jump from a tree or
rock into the water to swim away.
Marine iguanas live only on the Galapagos Islands and it is thought that they arrived to the
islands by floating from mainland South America on debris. They can dive as deep as 50 feet
(15m) underwater to feed on algae. They can stay under water for up to 20 minutes. In order to
stay down for very long in colder temperature water they have to first heat up their bodies in
the sun, slow down their hearts in the water, then re-heat in the sun again once they get out.

Basilisk - Source: Tad Arensmeier
Basilisks are great runners. When in danger, these lizards start running upright on their back
legs. They can even run fast enough to walk, or run really, on water. This has caused them to be
referred to as the "Jesus Christ Lizard".

Tuatara - Source: Tad Arensmeier
The tuatara has virtually remained the same for over 140 million years. The tuatara is a reptile,
but not in the lizard family, it is part of the family Rhynchocephalia (which translates to
Beakheads) which appeared over 220 million years ago. All the Beakheads, besides the tuatara -
2 species, became extinct about 60 million years ago. They are very rare, nocturnal animals.

Chuckwalla - Source: Tad Arensmeier
Chuckwallas are rock dwellers in the Southwest USA and Mexico. When threatened, they crawl
into crevices and puff-up their bodies so that they are tightly wedged in and nothing can yank
them out.
Lizards have crude third eyes on top of their heads that senses whether it's day or night.

elongated ribs which they can expand and retract. The wings are brightly colored and for this
reason they are also called the "butterfly lizard".

Gecko
The Gecko is the only lizard and reptile that speaks or barks. Many species are well known for
their specialized toe pads that enable them to climb smooth and vertical surfaces, and even
cross indoor ceilings with ease. There are an estimated 2,000 different species of geckos
worldwide, with many in existence still yet to be found. Just recently a 100-million-year old
gecko species was discovered in the Eastern Himalayas.

intimidate adversaries. They open their frills around their necks and hiss when threatened.

and Australia. Their counterpart in the Americas would be the Iguanidae. Some agamids enjoy
the water and others prefer the trees.
