AnswerYes,there is only one poisonous species in the world named Heloderma inhabiting Central America.
Answer
Incorrect. There are two poisonous lizard species in the World: Gila Monster, and the Mexican Horned Lizard.
The real answer
no there are two the Mexican beaded lizard and the Gila monster that's the right answer
That is actually incorrect as well.
There are 3 lizards that contain posion glands. The Gila Monster, the Mexican Bearded Lizard, and the Komodo Dragon.
Originally the Komodo Dragon was thought to kill its prey using The bacteria in their mouths. But just this year we were able to dissect and identify that they do indeed have poison glands in which they use to kill.
incorrect again the komodo dragon is not poisonous on the Gila monster and something else i forgot lol
There are about 1500 species of lizard that have poison glans. The komodo was thefirst to be identified, except for the commonly know and mentioned two. After that about 1500 species have been confirmed to have poison glans. they were evolved a long time ago and many species lack a means of utilizing the poison and usually the poison is very weak. snakes took a step forward on the lizards with their fangs.
Edit: These lizards are venomous, not poisonous.
It has been confirmed that the Komodo Dragon does acutally have poison
Two
Venomous snakes include several families of snakes and do not form a single taxonomic group. There are many venomous snakes.
Venomous snakes are often said to be poisonous, although this is not the correct term, as venoms and poisons are different. Poisons can be absorbed by the body, such as through the skin or digestive system, while venoms must first be introduced directly into tissues or the blood stream (envenomated) through mechanical means. It is, for example, therefore harmless to drink snake venom as long as there are no lacerations inside the mouth or digestive tract.
There are however two exceptions: the Rhabdophissnakes (keelback snakes) secrete poison from glands that it gets from the poisonous toads that it preys on; similarly certain garter snakes from Oregon retain toxins in their liver from the newts they eat.
In total, there are about 2,700 different species of snakes around the world. Out of these 2,700 species of snakes, only about 375 are considered to be poisonous and deadly.
Gila monster and Mexican Beaded Lizard are the only two poisonous lizards
there are only 5 lizards that can kill you such as the killer iguana
A lot
there are 4 or 5 kinds that fly
There are over 1000!
There are about 25 Chameleons in Arizona.
No, rat poisoning can not kill lizards.
There are 100 kinds of reptile in the amazon rainforest.
cats, wolves, foxes, lizards, fish, amphibians, and many many more
In practice it is more of a web than a chain, because there are many other kinds of animals and plants that would play roles, and there are many kinds of ants, lizards and hawks that do not eat each other. Still, loosely speaking, a few kinds of lizards frequently eat ants, and others, such as the horned lizards (Phrynosoma species) and the thorny devil (Moloch horridus) hardly eat anything else. Many kinds of ants will eat in turn eat s lizard in turn, if they find a dead or very small lizard. Some kinds of hawks will eat some kinds of lizards (though some, such as the snail kite, Rostrhamus sociabilis, do not). Some kinds of lizards, such as some large monitor lizards will eat any kind of hawk they can catch, and practically any other kind of bird too. Some other lizards eat carrion if they find any, and so they will eat dead hawks. So do many kinds of ants.And that does not even count the thousands of other species that play their parts.
no they can not
Dragons dont exist. if you mean lizards, there's over 5600 species of lizard.
all animals kill other animals
You can now add the Komodo dragon to your list of poisonious lizards, so, now there are three of them in the world. Except that komodo dragons are not venomous they have deadly bacteria in their saliva but have no venom glands to speak of. So the count remains two.
camel ions are kinds of lizards that blend into their informants
