The lizard is one of the most widespread groups of reptiles, with over 7,000 species worldwide. These creatures can be found on all continents except Antarctica, and on most oceanic islands. They are cold-blooded and use their tongues to detect prey. While male lizards typically have elaborate body ornamentation, females are often less elaborate.

The coloration of animals may be used as a means of communication and display. Coloration of lizards may be dependent on diet, temperature, and abiotic factors. Thus, a robust and stable metric is needed to quantify color. For example, lizards’ ventral coloration changes as temperature increases, from green to blue hues. High temperatures are difficult to measure for determining the exact saturation.
Male lizards may have a variety of different ornamentation. These may include extended throat fans, horns on the head, or tail crests. Some male lizards have multiple crests on their tails.
Female lizards lay soft, leathery eggs
Unlike snake eggs, which are usually hard and cracked, lizard eggs are soft and leathery. Although they remain soft during the incubation stage, they can harden if exposed to high humidity or low temperatures. To ensure the safe hatching of eggs, female lizards go through a series of contraction-like muscle spasms. During this time, the eggs are protected from damage.
The eggs of lizards are small and white in color. They tend to have pink veins when they are ready to hatch. They are also delicate and easily damaged by turning, moving, or overheating.
lizards detect prey with their tongues
Most lizards use their tongues to sense the environment, which can be extremely useful for finding food. They use the scent particles emitted from prey, which float around in the air, to gather them in their mouths and sense the presence of a predator. Snakes use the same method to detect prey.
In the water monitors, the tongue forks on the tip of the tongue provide directional cues that help them find prey. Their tongues also sample their environment, transferring chemical compounds to a sensor at the roof of their mouth. These lizards have the longest tongues of any limbed lizards.
lizards are cold-blooded
Although they do not produce any heat of their own, lizards can regulate their body temperature. They warm themselves by absorbing heat from the ground or sun. If the temperature inside of their bodies rises too high, they will retreat into the shade to cool down. Some lizards can also change color, becoming darker in color to better absorb heat.
However, some lizards can endure very cold temperatures. In fact, some species are able to hibernate, changing their color to blend into the snow. This helps them stay warm and avoid predators. A few species can even survive subzero temperatures. Examples of such creatures include the wood frog and the three-toed skink. Most other lizards, however, will not survive freezing temperatures.
They can walk on water
A team of researchers has discovered that lizards can walk on water. The researchers from Oxford University, California Berkeley, the Max Planck Institute, and the Georgia Institute of Technology studied how lizards move across water. They conducted a series of experiments and studied high-speed video of lizards walking on water. Using these results, they calculated how much force was produced by the animal’s movements.
Using their paws to row, lizards can run and walk across the water surface. In doing so, they create an air bubble that enables them to move forward. Their feet are webbed, which reduces the downward forces. They also have large hind feet with flaps of skin between each toe.
They can smell stuff with their tongues
Many lizards can smell stuff with their tongues. For example, monitor lizards have a strong scent that they can detect from a distance, and may use this scent to avoid larger predators. They also use this scent to avoid predators that have a powerful sense of smell, such as Komodo dragons. Some wild-caught monitors have even been found with pieces of aluminum foil and porcelain eggs, which were probably once sat on by chickens. In addition, spiny-tailed monitors can smell blood and will attempt to eat injured limbs.
Lizards use their tongues to pick up tiny particles of scent, and flick their tongues out to collect them. They use this information to find food, mates, and detect threats. These creatures don’t have a normal nose, so their tongues are essential to detecting their environment.
