Make this better Iguanas, Iguanas are vicious monsters you want to stay away from. These monsters are not trained. These beasts are cold blooded and also in the alligator specious and more. One reason these iguanas are beasts is because they sit in the sun all the time and if your dog is walking by and an iguana sees it, well the dog is probably some new space in the backyard next to mr. down the toilet; fish so that is one reason. The second reason is, if you have any plants of any thing that has some fruits or vegetables they will come and eat your fruits and vegetables just because they want to most of the time they aren't even hungry they are like alligator they will eat till the stomachs explode because they aren't hungry they just want to eat everything they see. The last reason is if you want to go fishing and you have an iguana in your neighborhood and there is very few fish in your lake, well most likely it was the iguana but it could be the alligators or birds, another reason is because if you have small children or are one you might not want to get into an eye to eye battle with and iguana because they sometimes eat what they see so you might become its snack.
If you come across one of these savage beasts you would want to look at it while you back up slowly until you are far enough where you know you can out run it. These beasts are as fast as an alligator so don't think that they won't catch you if you walk away with your eyes off it, it is like an alligator wanting to handle this situation just like you would handle an alligator. You want to look at it and back up slowly till you are far enough distance till you know you can outrun it or if it is chasing you, you should run in zig zags until it tires out then run away to a safe place.
A way to prevent these beasts from being around is by calling an animal control inspection to scope out where you live and make sure there are no iguanas or tracks of them either. A way to get rid of them if there are iguanas is to call animal control and tell them to come get it, but if it is too close to you for that then you want to make loud noises and make yourself as big as you can, kind of like a bear.
