1) False! Iguanas do not come from Africa, but from the tropical forests of Mexico, Central America and South America.

2) B & E - These two foods, spinach and cheese, are foods that should not be a part of your iguanas diet very often. Spinach makes a good treat every now and then, but it is not healthy for your iguana to eat it very often. Cheese and other dairy products, along with insects and meat, are not good iguana foods at all. They should be avoided.

3) B - 90 to 95º F is the correct temperature for your iguana's basking spot. Remember - your iguana is cold-blooded, and needs to have a variety of temperatures in his habitat so that he can regulate his temperature by moving around.

4) False! Like all animals, iguanas need fresh water. They may not drink very often, because they get water from their wet salad, but they do drink sometimes. It is very important that your iguana have a bowl of fresh water in his habitat all the time.

5) C - 6 feet, 15-20 pounds. A typical adult iguana can reach up to 6 feet long (including the tail) and can weigh in at 15-20 pounds! That's one big lizard!! Not all iguanas will get that big, but they all will continue to grow throughout their lifetime. That is why it is so important for you to provide you iguana with a nice big habitat.

6) A - calcium. Iguanas need a balanced diet that contains all of the nutrients listed in this question (calcium, vitamin A, iron, protein and vitamin B), just like you do. However, calcium is the most important one your iguana needs to stay healthy. Calcium makes your iguana's bones strong and helps her avoid Metabolic Bone Disease.

7) B - Iguanas need to bask in UV light. Without UV, your iguana cannot make vitamin D3, and she will become sick. Vitamin D3 helps your iguana's body use the calcium from her food.

8) C - Younger, smaller iguanas have many enemies. Being able to lose its tail gives an iguana a chance to escape. Tails can grow back, but they are never as pretty as the original. Be sure to never pull on your iguana's tail, or pick him up by his tail - otherwise it may fall off!

9) True! Like most reptiles, iguanas lay eggs. The eggs have a leathery shell. Female iguanas can lay eggs every year! If the female has not mated with a male, the eggs will be infertile. That means that they will not have babies growing inside, and they will not hatch. In the wild, a female that has eggs in her belly (we call that "being gravid") will dig a nesting hole in the ground and will lay her eggs in the nest.

10) E - A well-cared-for iguana can live 15 or more years! That is why you want to be sure to take good care of your friend -so she can be with you for a long time to come!

How did you do?
