Lizards are widespread groups of reptiles with over 7,000 species. They can be found on all continents, except Antarctica, and in most oceanic islands. These animals have a scaly skin and a clear membrane that protects their eyes from dirt. Listed below are some facts about lizards.
lizards are venomous
There are two main lineages of lizards. Both have venom glands and secrete venom. Though the venom glands in lizards are not the source of the toxins, they do help to kill their prey. In addition, the venom of lizards can cause prolonged bleeding and rapid swelling.
While there are many lizards that are venomous, not all of them can harm humans. Most lizard species do not seek out humans to attack them, but some are. These lizards may be more aggressive towards humans if they are separated from their mates.
they hunt for prey
Lizards use their senses to hunt for prey. They have a keen sense of 도마뱀분양 smell and can detect pheromones, though they lack external ears. They can also manipulate their eyes, and some can even look both forward and backward at the same time. Some lizards are known to feed on insects, while others depend on touch and their keen vision to hunt for prey.
Lizards are known to hunt for a variety of prey, from insects to birds. Some lizards are omnivores, eating plants, eggs, and other prey. Other lizards eat other lizards, while others feed on insects. In addition to insects, lizards also feed on fruit.
they have a clear membrane that shields their eyes from dirt
Most lizards have eyelids that cover their eyes and use blinking motions to keep their eyes clean. However, geckos don’t have eyelids and use a thin membrane to shield their eyes. In addition, lizards clean their eyes with their tongue. Some of them can even communicate with other lizards using distinct body parts.
Lizards have a membrane on the front of their eyes called the nictitating membrane. The membrane covers the anterior corner of their eyes and is transparent. Their eyes are also protected from debris and other objects.
they shed their old skin in one piece도마뱀분양
Lizards shed their old skin in one or more pieces, but it’s important to remember that the process is different for different species. While snakes and tarantulas shed their skin in a single piece, most lizards shed in patches. Some even climb out of their old skin.
Snakes, meanwhile, shed their skin in one piece, including the brille, which is the ocular scale. This process is critical to the snake’s vision. By contrast, lizards shed their old skin in pieces, making the process more difficult and time-consuming.
they are territorial
Lizards are territorial in many ways. Their aggressive displays are especially assertive, but they can also be challenging. Usually, these displays are initiated by adjacent dominant males approaching a common territorial boundary. When an intruder approaches, the defending male turns broadside and expands his dewlap and nuchal crest.
Lizards also use their displays to communicate their status. They may choose a more impressive colour for their displays, which may reduce intraspecific fighting. Alternatively, they may opt to flee from conflict. However, these displays are symbolic in nature, and natural selection is likely to favor symbolic displays that achieve the same goals as fighting without harming conspecifics.
they lay eggs
Lizards lay eggs as a way to produce offspring. Female lizards will lay a clutch of eggs and then separate them for about a month. In the mean time, the female will replenish her fat reserves and nutrients. When the time comes for her to lay eggs, she will find the best spot to lay her eggs.
Lizards will then begin to grow inside their eggs until they are ready to hatch. This process is accomplished by using the claw or the egg tooth to pierce the eggshell. If a lizard does not have these tools, the eggshell will crack, and the lizard may die. The process of egg formation in lizards is called viviparity, and the developing embryos will get their nutrients from the mother’s body. Once the embryos hatch, they will be completely formed.
