There are a variety of lizards that live in the world. There are thousands of lizard species and each has its own unique characteristics. There are lizards with frills. Some lizards have two legs and some have no legs at all.

"lizard" isn't related to a single scientific group. The lizards and snakes are part of the same order. The Integrated Taxonomic Information System is a partnership of North American agencies, organizations and tax. ITIS doesn't consider lizards to be valid scientific groups if they are grouped under the sub orders Lacertilia or Sauria.

Are lizards dinosaurs?

lizards are not dinosaurs though they are reptile. The two groups have different body plans. The lizards are walking in a side-to-side motion. According to the American Museum of Natural History in New York, dinosaurs had an upright stance with their legs under them.

Taxonomy of lizards.

The kingdom is called Animalia.

Chor data is called phylum.

The class is called Amphibia.

There is an order for "Sultana".

Itis is the source.

The extinction of nonavian dinosaurs 66 million years ago was one of many mass extinction events that the lizard has survived. The dinosaurs first appeared about 25 million to 201.3 million years ago, and the lizards probably preceded them.

"Based on a new estimate of the rate of evolution of lizards, we can now place the origin of these reptiles in the late Permian period, about 260 million years ago," wrote a researcher in The Conversation.

Types of lizards

There are different shapes and sizes of lizards. Komodo dragons are from Indonesia. The Komodo dragon at the National Zoo in Washington, D.C. is the largest dragon on record at over ten feet in length.

The Komodo dragon is the biggest lizard. It's difficult for scientists to know which lizard is the smallest because it's so small. According to a 2001 study in the Caribbean Journal of Science, the smallest lizards on the planet were the Jaragua lizards. The lizards were smaller than any known bird or mammal at the time.

A study was published in the journal Scientific Reports in which a chameleon named Brookesia nana was described. The males of B. nana are smaller than the females. The females of this species are larger than the lizards.

The general body plan of reptiles is similar to that of mammals and humans, so it's fascinating to see how small these organisms can be.

Some lizard species have other features that make them stand out. The name "flying dragons" comes from the fact that they glide from tree to tree in Southeast Asia using a thin membranes between their legs. Basilisk lizards from Central and South America are so fast on their hind legs that they can run on water. It's earned them the nickname " Jesus Christ lizard" due to the fact that they do this to escape.

lizards can break off their tails if they are caught by a predator. The new tails aren't perfect copies of the old ones. The bones in the original tail don't grow back in the same way as the new ones.

Where do lizards live?

There are lizards in all sorts of habitats. The Texas horned lizards spend a lot of their time in loose sands in northern Mexico and the south central U.S., including most of Texas. Eastern fence lizards like to live in areas with trees.

Basilisk lizards spend a lot of their time in the water. The Natural History Museum in London states that marine iguanas from the Galpagos Islands dive into the ocean to feed off seaweed.

Endothermic animals, such as mammals, can regulate their own body temperature, but lizards can't. They are often referred to as "cold-blooded." lizards can be seen basking in the sun to warm up during the day

Most lizards spend most of their time alone or with other lizards of the same species. There are exceptions to the rule that lizards don't spend time with other lizards. According to research by the University of California, Santa Cruz, desert night lizards are found in family groups.

What do lizards eat?

A lot of lizards eat other animals. According to the Zoological Society of London, Komodo dragons can consume up to 80% of their body weight in one sitting. In Australia, the central bearded dragons eat fruit and leaves along with ants and smaller lizards. There are lizards with specialized diet, such as the marine iguanas, which are known to eat insects and crustaceans.

Are lizards poisonous?

Some lizards are venomous, meaning they inject harmful venom. According to the American Museum of Natural History, venom can be used to hunt prey or defend themselves against predatory animals. A gila monster can bite another animal for a long time. Humans are not killed by the venom.

Do lizards lay eggs?

Some lizards give birth to live children. When a male lizard tries to attract a female mate with a display, it's usually the beginning of lizard breeding. Frilled lizards are named because of their frills around their neck, which they use to scare away predatory animals. According to the Northern Territory Government, these lizards lay up to 23 eggs between November and February. According to the Woodland Trust, common lizards give birth to up to 10 live young in July.

The majority of baby lizards are self-sufficient from birth. According to the San Diego Zoo, young lizards range from 18 months to 7 years of age. The life spans of lizards are vastly different. Labord's chameleons can only live in their native habitat for a short time, while other lizards can live for a long time. The longest- living lizards are the Grand Cayman blue iguanas. A captive blue iguana is thought to have lived 69 years.

The Florida family is terrifies by a 6-foot long lizard.

Are lizards endangered?

22% of the world's reptile species are at risk of extinction, including many lizards, according to an assessment done by the International Union for the Preservation of Nature. Habitat loss due to agricultural expansion is one of the biggest threats to reptiles.

There are two lizard species that could disappear in the next few years. Climate change and residential and commercial development are threats to the survival of the Komodo dragon. The study authors recommended that the species be listed as critically extinct because it lives in a small area that's getting smaller due to agriculture.

The Campbell's alligator lizard is one of the critically-endangered lizards listed on the organization's website.

A threat to species that are from the wild is posed by lizards. Even lizards that are bred in captivity are sometimes caught in the wild to supply the trade.
