We got inguanas running all over the place in Cape Haze and Gasparella Is. FL but they aren’t 4-6’ long. Thousands! They are not a native species. I’m afraid to think what else is around, we also have exotic Amazon River fish in the canals. People buy exotic pets and then they release them when they tire of taking care of them.
Are the iguanas big or aggressive enough to cause a danger to the public?
Some of my Australian friends consider it a sign of good luck when lizards take up residence in their gardens, because they eat rodents and some poisonous insects and thereby are a benefit to gardeners.
They are very small lizards though, typically no more than 1 1/2 feet long
