Lizards are distributed throughout the world, and as the San Diego Zoo notes, most of them live on the ground. Other common lizard dwelling places are underground burrows (especially in deserts), under rocks, marshy bogs and in trees.Know More
Lizards are cold-blooded animals, meaning they do not have a high enough metabolism to regulate their own body temperatures. This means that globally distribution is higher in the tropics, sparser in temperate regions and entirely nonexistent at the poles. Lizards rely on the ambient temperature of the regions they inhabit to provide them with sufficient energy to remain active. Snowy mountain peaks, icebergs and even temperate regions in the winter are all exceedingly inhospitable places for lizards to live.
On the other hand, deserts, which are primarily inhospitable to most forms of life, provide lizards with all the heat they could ever need. The desert monitor lizard's range includes the Sahara, and the only two venomous lizards, the Gila and the horned toad, both make the deserts of the southwest United States their homes.
Of the familiar lizard families, marine iguanas are great swimmers. Chameleons are all tree dwellers, along with anoles and skinks. The enormous monitor lizards are a ground-dwelling group.Learn more about Lizards
Geckos are types of lizards, but have several physical features, such as shorter and broader heads and sticky feet, that distinguish them from other types of lizards. Geckos and lizards live in many areas around the world and are particularly well-suited for life in hot and dry locations, such as the American southwest and deserts in the Middle East.Full Answer >
The average lifespan of a lizard usually runs between one and 30 years, with a median of 10 years. Because there are over 5,000 different species of lizards, the lifespan varies from species to species.Full Answer >
Lizards do pushups to communicate with other lizards, both male and female, especially if there is a lot of environmental noise that makes it difficult for the lizard to communicate vocally. Lizards often follow up the pushups with the head bob, which shows personal strength and conveys a territorial message to other lizards.Full Answer >
The frilled lizard is native to Northern Australia and Southern New Guinea. They inhabit tropical and warm temperate forests, as well as woodlands. These lizards are arboreal, spending most of their lives in trees, only descending for food or to engage in territorial conflicts.Full Answer >
