They’re far more likely to flee from us than attack, as they are very shy animals. What’s more, their venom just isn’t potent enough to be fatal to humans. More recent research suggests most lizards do, in fact, possess weak, primitive venom glands, but they are only harmful to small prey animals.
There is a positive correlation between size and viability of eggs, with larger geckos having eggs which were more likely to survive. Territorial males will display larger heads, with a more pronounced head shape. This increase in head size incurs the cost of a poorer performance in escape sprint time. This suggests selective pressure prioritises the biting force capacity of the male, over their capacity to escape quickly. On the contrary, increases in female head size are met with a proportionate increase in hind limb length and no decrease in speed.
The Common Lizards Of India!
Because it is also true that there are certain lizards that are poisonous and can harm humans. As we have already established that many lizards and even the house lizard are nonvenomous, however, they are still harmful to humans. Additionally, bites by large species can cause severe damage. Since these animals are carnivores, their teeth are sharp and designed for ripping through meat. Thus, a larger lizard’s bite will cause more bleeding and can possibly tear through flesh and arteries. A monitor lizard’s bite is one of its most dangerous traits and it can cause severe pain.
Taksande AM et al., reported a lizard bite in Indian child presented with excessive crying, swelling and bleeding from the bitten site, who recovered without any complications . Vikrant S and Verma BS reported acute kidney injury following monitor lizard bite . Autonomic storm like features are usually seen with scorpion sting envenomation, but rare with lizard bite. The Komodo Dragon is the largest lizard in the world, and also one of the most dangerous monitor lizards. Adult Komodo Dragons weigh between 150 to 200 pounds. Record species have been reported getting as large as 300 pounds and growing 10 feet long.

Eliminate these sources, and the lizard can move to another place. Try to keep the lighting to the minimum before you ward off the pest. Then it is vital to seek the services of a lizard control professional. They will come to your house and find the source of recurrence. If steps are properly taken, you can find an easy solution to the problem.
They grow to a length of between 7.5–15 cm (3–6 in), and live for about 7 years. These small geckos are non-venomous and not harmful to humans. Most medium-sized to large geckos are docile, but may bite if distressed, which can pierce skin. The animal is very adaptable and may prey on insects and spiders, displacing other gecko species which are less robust or behaviourally aggressive. In parts of Australia and Papua New Guinea they are often confused with a similar native lizard, the dubious dtella. Bites are only inflicted when they are manipulated or when they are cornered and feel threatened.
Venomous Lizards: The Beaded Lizard
An arboreal reptile, Indian chameleon’s webbed feet, slender limbs, and a long tail allow it to easily grip and make balance on plant stalks. The lizard also has eyes that can rotate independently to locate prey. Having one of the fastest tongues that can shoot out to 1.5 times its body length within milliseconds, the chameleon can grab whatever it sets its eye on! Its preferred meals include vegetation and small insects such as grasshoppers, butterflies, and dragonflies– making it a crucial part of the ecosystem. The word Lizard itself can run a chill down one’s spine.
There are behavioural mechanisms of thermoregulation present, such as the selection of sunlight and the substrates on which they sit. The common house gecko is prolific through the tropics and subtropics. It is able to exist in an ecologically analogous place with other Hemidactylus species. Most recently, this species has also invaded the Caribbean Lesser Antilles, and is now present on Dominica and Saint Lucia. Their capacity to withstand a wide range of latitudes is also partially facilitated by their capacity to enter a state of brumation during colder months.
The eastern fence lizard grows up to 7.25 inches (18.5 cm). They are a member of the spiny lizard family and are native to South Carolina and Georgia. They are gray in color but can range from brown to black. These fast lizards are active and appreciate the heat, they are alert during the day taking refuge in burrows at night or when faced with a predator. The Mexican beaded lizard (H. horridum), a closely related species, is slightly bigger (to 80 cm ) and darker than the Gila monster, but otherwise looks similar. Many teeth contain two grooves that carry venom, a nerve toxin, from lower jaw glands.
Lizards are classed as venomous i.e. they can inject venom into your bloodstream when they bite you. However, there are very few lizards that are venomous mainly the Gila Lizard, and Mexican Beaded Lizards. As these lizards mature, they fade to gray or brown with males having orange heads with very powerful jaws.
The little brown skink can be easily distinguished from the other lizards due to its small size and its very small front and back limbs. The larger males tend to prefer tree-dwelling, where they sun themselves on exposed branches. The female may have black horizontal patterns on her back. During the breeding season, males can be identified for their bright blue patterns on their underside and chin.
I was intrigued about this Chipkali and this led me to research this lizard. There is some weak evidence to suggest a trend towards higher temperature for females, which has an evolutionary advantage of increasing the speed of egg development. However, there is no statistically significant data to support this. Frenatus was first collected in Acapulco, Guerrero, in March of 1895 and found to be well established there and in the surrounding regions by the early 1940s. Proper sanitation in the home will reduce lizard population. Fruit flies, mosquitoes, cockroaches need water for survival and reproduction.
An example of this is how the common house gecko can trigger an "avoidance response" in the mourning gecko, causing it to avoid a specific area where food may become available. This allows them greater access to feeding areas and territories, making them a highly successful invasive species. Although beaded lizard bites are almost never fatal, prompt medical attention is still necessary to treat them. Their hemotoxic venom can interfere with blood clotting and cause respiratory issues.
