It depends on the type, water or land. Watre iguanas use them to grip rocks so the current wont wash it way, the land and water iguanas use them for balance.
Iguanas do not have a prehensile tail.
No an iguana can only grow its tail , toe and nails back
It's tail can break off and it will grow back.
2 to 3 feet
Probably the same way as a dog.
The iguana height is 5' 7½" (1.71 m) from tail to head. This is the average but some may vary.
Iguana's have long tails because the tail provides an Iguanas main defense. Not only can they use their massive strong tail to whip the predator to either hurt it or startle it, but they also can drop their tails when they are in danger to distract the predator.
Iguanas can grow to 6 feet (1.8m) nose to tail.
A full-grown Iguana can reach 72 inches from the tip of its nose to the end of its tail !
Unless you want your iguana to get eatin, or your snake to get tail whipped, I wouldn't recommend it. I have an iguana, but it's a baby.
it has a sort of green flabby beard and it tail is a couple inches long.
The species with long tail, eyelids, and four sprawling legs is a lizard.
