I didn't realize there were so many species of lizards - there are over 6000!
Lizards are a widespread group of squamate reptiles, with over 6,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains.

Lizard
Lizards are a widespread group of squamate reptiles, with over 6,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic as it excludes the snakes and Amphisbaenia which are also squamates. Lizards range in size from chameleons and geckos a few centimeters long to the 3 meter long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Others are legless, and have long snake-like bodies. Some such as the forest-dwelling "Draco" lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with brightly colours, to attract mates and to intimidate rivals.
List of reptiles of Guatemala
This is a list reptiles in Guatemala, including snakes, lizards, crocodilians, and turtles. Guatemala has a large variety of habitats, from tropical rain forests, dry thorn scrubs, cloud forests, coastal marshes, pine forests, mountains and lowlands. This vast contrast in biomes makes Guatemala home to a large variety of herpetofauna. These include approximately 240 species of reptiles, subdivided in 3 orders and 29 families. Order: Testudines. Family: Cheloniidae  Sea turtles (Cheloniidae) are a family of large tortoises found in all tropical seas and some subtropical and temperate seas. Sea turtles evolved from land turtles about 120 million years ago and are well adapted to life in the sea.
Reptile
Reptiles are tetrapod animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. Because some reptiles are more closely related to birds than they are to other reptiles (e.g., crocodiles are more closely related to birds than they are to lizards), the traditional groups of "reptiles" listed above do not together constitute a monophyletic grouping (or clade). For this reason, many modern scientists prefer to consider the birds part of Reptilia as well, thereby making Reptilia a monophyletic class.
Lizard communication
Lizards are a diverse group of reptiles—there are nearly 4500 different lizard species, excluding snakes. They come in all shapes, sizes, and colors, and also vary widely in many aspects of their behavior, such as how they reproduce and forage for food. In addition to this extraordinary diversity in physical and behavioral characteristics, lizards have evolved many interesting ways to communicate. Lizards rely on many different sensory systems, including the visual, olfactory, and auditory systems. As these sensory systems have become more sophisticated, lizards have developed different modes of communication that incorporate these sensory systems, including visual, chemical, tactile, and vocal communication.
Snake
Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes. Like all squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca.
Evidence of common descent
Evidence of common descent of living organisms has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating that all life on Earth comes from a single ancestor. This forms an important part of the evidence on which evolutionary theory rests, demonstrates that evolution does occur, and illustrates the processes that created Earth's biodiversity. It supports the modern evolutionary synthesis—the current scientific theory that explains how and why life changes over time. Evolutionary biologists document evidence of common descent, all the way back to the last universal common ancestor, by developing testable predictions, testing hypotheses, and constructing theories that illustrate and describe its causes.
Sexual dimorphism
Sexual dimorphism is the condition where the two sexes of the same species exhibit different characteristics beyond the differences in their sexual organs. The condition occurs in many animals and some plants. Differences may include secondary sex characteristics, size, color, markings, and may also include behavioral differences. These differences may be subtle or exaggerated, and may be subjected to sexual selection. The opposite of dimorphism is "monomorphism". Common and easily identified types of dimorphism are ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles.
