Yes, lizards can hear. They may not have external ears like mammals do, but they can detect sound vibrations through their eardrums and inner ear structures. Lizards use their hearing to communicate, detect predators, and locate prey.
Describe excretory system of reptiles?
The digestive system of modern reptiles is similar in general plan to that of all higher vertebrates. It includes the mouth and its salivary glands, the esophagus, the stomach, and the intestine and ends in a cloaca. Of the few specializations of the reptilian digestive system, the evolution of one pair of salivary glands into poison glands in the venomous snakes is the most remarkable.
During development the embryos of higher vertebrates (reptiles, birds, and mammals) consecutively develop three separate sets of kidneys; these are arranged in longitudinal sequence in the body cavity. The first set, the pronephroi, are vestigial organs left over from the evolutionary past that soon degenerate and disappear without having had any function. The second set, the mesonephroi, are the functional kidneys of adult amphibians, but their only contribution to the lives of reptiles is in providing the duct (the Wolffian duct) that forms a connection between the testes and the cloaca. The operational kidneys of reptiles, birds, and mammals are the last set, the metanephroi, which have separate ducts to the cloaca. The principal functions of the kidney are the removal of nitrogenous wastes resulting from the oxidation of proteins and the regulation of water loss. Vertebrates eliminate three kinds of nitrogenous wastes: ammonia, urea, and uric acid. Ammonia and urea are highly soluble in water, but uric acid is not. Ammonia is highly poisonous, urea is slightly poisonous, and uric acid is not poisonous at all.
Among reptiles the form taken by the nitrogenous wastes is closely related to the habits and habitat of the animal. Aquatic reptiles tend to excrete a large proportion of these wastes as ammonia in aqueous solution. This method uses large amounts of water and is no problem for a freshwater resident, such as an alligator, which eliminates between 40 and 75 percent of its nitrogenous wastes as ammonia. Terrestrial reptiles, such as most snakes and lizards, must conserve body water, and they convert their nitrogenous wastes to insoluble, harmless uric acid, which forms a more or less solid mass in the cloaca. In snakes and lizards, these wastes are eliminated from the cloaca together with wastes from the digestive system.
Prior to the evolution of the metanephric kidney, the products of the male gonad, the testis, traveled through the same duct with the nitrogenous wastes from the kidney. But with the appearance of the metanephros, the two systems became separated. The female reproductive system never shared a common tube with the kidney. Oviducts in all female vertebrates arise as separate tubes with openings usually near, but not connected to, the ovaries. The oviducts, like the Wolffian ducts of the testes, open to the cloaca. Both ovaries and testes lie in the body cavity near the kidneys.
With the evolution of the reptilian egg, internal fertilization became necessary. The males of all modern reptiles, with the exception of tuataras, have functional copulatory organs. The structures vary from group to group, but all include erectile tissue as an important element of the operating mechanism, and all are protruded through the male's cloaca into that of the female during copulation. Unlike the penis of turtles and crocodiles, the copulatory organ of lizards and snakes is paired, with each unit being called a hemipenis. The hemipenes of lizards and snakes are elongated tubular structures lying in the tail. The penis of a crocodile or turtle is protruded through the cloacal opening wholly by means of a filling of blood space (sinuses) in the penis; protrusion of a lizard's or snake's hemipenis, however, is begun by a pair of propulsor muscles. Completion of the erection is brought about by blood filling the sinuses in the erectile tissue. Only one hemipenis is inserted into a female, but which one is a matter of chance. Unlike the penis of mammals, the copulatory organs of reptiles do not transport sperm through a tube. The ducts from the testes, as already mentioned, empty into the cloaca, and the sperm flow along a groove on the surface of the penis or hemipenis.
Are backyard lizards poisonous?
No - they're a non-venomous species. I couldn't find that much info - but I DID find something on Wikipedia - See related link the real alligator lizard are not the most venomous it is not the mostcommon lizard in living with people

Why does the armadillo lizard bites its own spiky tail?
Armadillo Lizards will bite on their tail and/or roll themselves into a ball when threatened. They also hide amongst rock crevices and inflate their bodies so they cant be removed. Hope that helps -FartingPenguin
Name of lizard with sticky feet?
The lizard with sticky feet is called a gecko. Geckos have specialized toe pads that enable them to climb and stick to surfaces such as walls and ceilings.
Yes, bearded dragons can bite if they feel threatened or stressed. However, bites are usually not severe and are more of a defense mechanism rather than an act of aggression. With proper handling and care, bearded dragons can become docile and less likely to bite.
Some lizards may eat seeds as part of their diet, but seeds are not a primary food source for most lizard species. Lizards are primarily carnivorous or insectivorous, meaning they mainly eat other animals such as insects, small mammals, or other reptiles.
How do thorny devils adapt to the desert?
Thorny devils are lizards that live in the Australian desert. On major adaptation that they have is the ability to change their coloration to light when it is hot and then to dark when it is cooler, thus either protecting themselves from the heat with light colors or taking advantage of the sun's rays to warm themselves by absorbing more with dark colors in the cold.
Why do lizards and cockroaches crawl on ceilings and walls?
Insects that have the ability to climb walls have fine hairs that help them stick to the surface they are climbing. Other insects have glands that secrete liquid on their feet that allow them to climb.
Flying lizards, also known as Draco lizards, primarily feed on small insects such as ants, termites, and beetles. They catch their prey with their long, sticky tongues as they glide from tree to tree in search of food. Additionally, they might also occasionally consume small fruits or vegetation.
Do you need a license in a Australia to keep a shingleback lizard?
In Australia, you typically do not need a license to keep a shingleback lizard as a pet. However, it is important to ensure that the lizard was not removed from the wild illegally, as this is a protected species in some regions. It is recommended to purchase shingleback lizards from reputable breeders to guarantee their legality and welfare.
How lizards break their tail as a way to escape from enemies?
I believe that what happens is that the predator catches the lizard by the tail, and then the tail breaks off and the lizard gets away, leaving the enemy there in awe with a tail dangling from his mouth. :] I believe the tail is mostly dead skin cells, and it can be regrown in a short period of time.

They make awesome pets! I have 3! They don't need light, though they have it. Mine are not tamed yet because I have only had them 2 weeks!
is it sold at pet stores?
if you want your lizards tongue and esophagus and possibly digestive tract to get swollen and possibly close leading to organ failure, or suffocation (a slow and painful death) then yes. yes they can.
Lizards can die from a variety of reasons, including disease, predators, environmental factors like extreme temperatures or habitat destruction, accidents, or old age. Additionally, lack of access to food and water may also lead to a lizard's death.
Why does lizards eat baby lizards?
Some lizards, like certain species of snakes, may eat baby lizards as a source of food because it provides them with necessary nutrients and energy for survival. This behavior is a part of their natural predatory instincts and helps regulate population levels within the ecosystem. Additionally, competition for resources may also drive some lizards to consume offspring.
What does a lizards diet consist of?
A lizard's diet typically includes insects, such as crickets, mealworms, and grasshoppers. Some lizards may also eat fruits, vegetables, and small mammals.
