Their digestive system is similar to other herbivores that exist solely on foliage such as horses, rabbits, and koalas. Known as hindgut fermenters , these animals have specific microbes and bacteria in their intestinal system that ferments their overly fibrous food in order to help absorb the nutrition properly.
Unlike us, their saliva contains no additional enzymes and is produced in a smaller amount. They are not equipped with the same teeth as carnivores or even traditional herbivores. They have plenty of those sharp little things of them! They are gulpers — ripping and swallowing whatever pieces you put in front of them in order to get it into their tummies and fast.
All the work they need to do to digest is done in the stomach and intestines. This means that your poor iguana is more susceptible to choking and painful blockages should you prep their food improperly.
If you stay within these sizes, you will not have to be concerned with obstructions and you can be assured that your iguana will have no trouble digesting and getting the maximum benefits from their meals.
In the wild, iguanas are used to variety. In fact, they can become easily bored when served the same meal every day. They naturally enjoy a wide variety of plants, have individual tastes and have even been known to travel long distances in order to satisfy a craving for a particular food. The number one preventable cause of health issues and fatalities in iguanas is a poor diet.
However, this is where things can get confusing. Scientists and veterinarians are still learning how to prevent bone disease and illness in these reptiles and a great deal has changed over the last twenty years. Animal protein in the form of crickets or mice can overload their systems resulting in kidney damage, kidney failure, and even death.
They are much healthier on an exclusively plant-based diet. This begs the question: which vegetables are best, and which should be avoided? The following list of vegetables contains the ideal ratio of calcium to phosphorus that your iguana needs to keep his bones strong and healthy. Metabolic bone disease is the most common condition found in neglected iguanas and it is almost entirely due to an imbalance of this particular ratio.
Unlucky iguanas who are fed nutrient sparse foods such as iceberg or romaine lettuces as their main dish will eventually develop this devastating condition, resulting in fragile, easily broken bones throughout the body. Kale, Mustard Greens, Red and Green Cabbages all contain goitrogens — substances naturally found in these foods which can cause hypothyroidism in large amounts.
Spinach, Swiss Chard and Beet Greens are very nutritious, but they contain oxalates which can prevent absorption of minerals such as the all-important calcium. Not only will this stop your iguana from turning up his nose at your carefully prepared meals, but it will give him additional minerals and vitamins missing from his leafier diet choices.
Everyone needs a treat now and then and your iguana is no exception. A nice way to think of these treats is as a kind of salad dressing.
These fruits and flowers are best served as toppings to their regular meals. Think of them as you would sprinkles on ice cream or a lick of butter on toast. En s ure that these flowers are either homegrown with no additives or pesticides or purchased from a grower with the same conditions. The chemicals used in conventional florist shops can be extremely harmful. The authentic diet of the iguana is almost impossible to recreate in captivity.
One of the major steps you can take is to ensure that the fruits, vegetables, and flowers you serve him are organic. Even better, consider growing your own!
The Green Iguana Iguana Iguana , also known as the American Iguana, is native to South America, a large arboreal reptile they are what springs to people's minds when they often see or hear about a reptile as a pet. Strangely enough, they are not nearly the most popular reptile in the pet industry, but there are a lot of Iguana owners, nonetheless.
The Green Iguana is a herbivorous reptile, eating fruits and vegetables solely in their captive diet. Although Iguanas have been observed consuming invertebrates in their natural habitat, there is some debate over whether they should be offered animal protein in captivity.
It's not something they require, and it seems to be more of an opportunistic thing for them in the wild. There are also several commercial products available that have been formulated from fruits and vegetables to provide a sustainable diet for them, which can be used as their whole diet or to supplement their diet alongside fresh foods.
In captivity, some certain fruits and vegetables are better than others that are more healthy than others, and you must provide them with the correct ratio of the various nutrients that they require to stay healthy. Iguanas that are held in captivity are fed fruit, flowers, leafy greens, turnip greens, and shoots of plants, each of which contains varying amounts of vitamins, minerals, and nutrients.
So what should you feed your pet Iguana? All Iguanas should be offered food daily, regardless of age, which is in contrast to most other reptiles, which require different schedules depending on age. Older Iguanas may not be as hungry, and it is okay to skip a day here and there, but with baby and juvenile Iguanas, they must be fed daily.
Foods should be chopped into sizes appropriate for the size Iguana and offered after the foods have been treated with the proper supplementation. Oxalates bind calcium in the body, and they should be restricted in the diet of any species that requires a lot of calcium in their diet, such as the Green Iguana. Calcium is used to maintain a healthy bone structure. We will now examine the five most common types of iguanas, uncovering their habitats and discovering what they eat in the wild.
Green iguanas also known as American iguanas are by far the most common iguana found in the Americas. Green iguanas are arboreal, meaning they live up in the canopy of trees for most of their lives, only coming down occasionally to change trees, mate, or lay eggs. Green iguanas in the wild are primarily herbivores, meaning their diet consists almost entirely of plants like leaves, fruits, and flowers. Since they are found in numerous regions across the Americas, plant availability in their specific location and habitat determines the types of plants they eat.
On rare occasions, green iguanas in the wild have been known to eat eggs, leaf dwelling insects, and snails. One of the most common lizards found in the Mojave and Sonoran deserts northwestern Mexico and the southwestern United States is the desert iguana. In addition to green iguanas, you may also encounter the invasive Mexican spiny-tailed iguana and the black spiny-tailed iguana.
All three of these invasive species are considered large iguanas. Green iguanas can grow up to 17 inches from snout to tail, while the Mexican spiny-tailed iguana can grow up to 18 inches. Iguanas are considered primarily herbivores, meaning that the bulk of their diet consists of plant matter.
In fact, these lizards can survive off of plant matter, alone. The question is, what plants do they love to eat and what plants do they hate? Iguanas are particularly fond of most fruits and flowers as well as new growth that is tender and non-toxic. The list of plants iguanas eat includes:.
If you or a nearby neighbor are growing any of the above plants, you may be more likely to encounter iguanas in surrounding trees. Iguanas spend the majority of their time in trees, coming down to mate, eat, and relocate to a more hospitable tree.
That means that they like to make sure that they have a steady source of food and water close to their tree of choice.
