The animal on the cover of Essential PHP Security is a monitor lizard (Varanus). It is a reptile found in the tropical and arid settings of Africa, Australia, Southern Asia, and the Malay Archipelago. There are approximately 50 species of monitor lizards, which are believed to have evolved from a common ancestor 45 million years ago. Depending on the species, monitors vary in coloring, markings, size, and weight. The largest monitor lizard is the Komodo dragon, which can weigh as much as 364 pounds and be up to 9 feet long. The smallest, the short-tailed monitor, is only around 3 inches long. Monitors are characterized by a flat head with a bony skull, which protects their brains from damage when they swallow their prey whole. Other characteristics include long, sharp claws and knife-like teeth that are curved inward.

Their diet consists of such fare as snails, beetles, grasshoppers, scorpions, crabs, fish, crocodile and bird eggs, and small rodents. Larger monitors will dine on carrion.

The monitor lizard holds its head up, giving it the appearance of being alert. When threatened, it intimidates its predators by inflating its throat and hissing loudly, while contracting its rib cage to make its body appear larger. Typically, a monitor's first reaction is to flee from danger, but it can become an aggressive opponent if cornered. Its strong jaws enable it to inflict serious wounds to enemies and prey alike. A monitor will also rear back on its hind legs and use its tail to deliver a stinging blow when attacking. Unlike some of its reptile cousins, a monitor cannot regenerate a new tail if it loses the one it was born with.

During breeding, males will become aggressive and fight for females. The female monitor typically lays 7 to 35 leathery eggs and, depending on the species, will make a nest in holes on riverbanks or in trees. Monitors that lay eggs on land cover their eggs with rotting vegetation to keep them warm. Eggs incubate for 8 to 10 weeks; the young cut their way out of the shells using a sharp egg tooth.

To date, it is legal to own monitor lizards as pets in the United States without a permit. However, the American Federation of Herpetoculturists (AFH) provides guidelines for potential owners that include keeping the lizards in escape-proof cages with good ventilation and handling larger species only when in the presence of another person. When handled from a young age by humans, monitors can become quite tame and adapt well to captivity. Potential owners should not be squeamish about feeding them a steady diet of live rodents.
