Now many people like to keep lizards as pets. On the one hand, most lizards are small and look much more lovable than snakes. On the other hand, many of them are non-toxic and therefore relatively safe. So are all lizards non-toxic? The answer is No.
In fact, there are two kinds of poisonous lizards in the world: Mexican lizard and American lizard. The former has four subspecies, with a total length of more than half a meter and a large one of up to 1 meter; The latter has two subspecies, with a total length of 20-30 cm and a large one of up to half a meter. The poisonous lizard has a big head, a round kiss, a thick and strong body and a slow action. It likes to inhabit in a dry environment. It is an oviparous animal. The body surface is covered by small but non overlapping scales, with dark body color and yellow or pink stripes.
They are carnivorous animals and eat mice, insects or bird eggs. Their toxins are often used to hunt and defend enemies, and their fangs are located on the third tooth behind the lower jaw. Poisonous lizards inject poison in a different way from poisonous snakes. When hunting, they will constantly grind holes in their prey with poisonous teeth, and then inject the venom directly into the wound through their teeth. Once bitten by a poisonous lizard, people often feel nausea, vomiting or fever.
In addition, the largest and oldest existing lizard, Komodo dragon (giant lizard), is distributed on the islands of Indonesia. Its maximum length can reach 3.5 meters and weighs more than 100 kg. Originally, it was believed that Komodo dragon killed its prey by virtue of a large number of pathogenic bacteria in its mouth, and the prey died only because it was infected with pathogenic bacteria. In recent years, the research team of Professor Frey of the University of Melbourne in Australia overturned this statement. They found that the lower jaw of Komodo dragon contained glands secreting lethal venom, which contained highly active vasodilator and anti blood agglutination components. After the prey is poisoned, the blood pressure will decrease rapidly, the blood flow in the wound will not stop, and it will coma in a short time.
At present, alien species are very common in China, so if you also like raising lizards, you must find out its species first.
