One strain of green iguana from South America has a reddish cast to the head. Young iguanas are generally brighter green or blue with some dark brown striping on the body and tail. The striping pattern of some actually results in a reticulated pattern.
This coloring helps to camouflage them as they live among the bright leaves in their natural habitat. As they age, the green color becomes less intense. The dark patterns, striping, or banding on their bodies and tails become more intense as the iguana reaches approximately 18 months of age. The heads of older iguanas tend to be paler, appearing gray or almost white, as seen in the iguana on the left.
Male iguanas develop an orange to orange-red coloring as breeding season approaches. In some iguanas, the orange color may be diffuse over the entire body.
In others, the orange can be concentrated in several areas including the dewlap, spikes, body, and legs. Female iguanas can also develop this orange coloration, though it is usually less intense. Dominant males and females often retain the orange color past the breeding season. The orange color will persist if there are other iguanas present, or even dogs, cats, and people, over whom the iguana feels dominant.
Environment, especially temperature can influence the color of an iguana. Iguanas tend to become darker if they are cold. The darker color helps them absorb more heat. Color change in response to temperature is called "physiological thermoregulation. Several weeks prior to shedding, an iguana's skin may appear dull and take on a gray or yellowish-gray cast.
Unlike snakes, iguanas, and other lizards do not shed the skin over their entire surface at one time. White patches will appear where the skin loosens, just prior to being shed. Iguanas with liver disease may appear yellow, especially their mucous membranes. This yellow color should not be confused with the yellow cast that may appear prior to shedding.
Red mite infestations may cause some scales on the skin to become raised and black. These are generally found on the ventral abdomen belly and limbs, and should not be confused with the normal striping or reticulated pattern. Darker raised areas can also be a result of fungal infections. The skin over injuries will usually appear pink, smooth, and scaleless. Therefore, if you find your iguana changing their color except during mating or shedding, you should look for the underlying reasons.
For males, the colors change to very bright orange to show dominance during the breeding season. As for females, their color changes to orange to become noticeable. Iguanas come in different colors known as morphs. There are many types of iguanas , to produce unique morphs, breeders selectively breed them, producing more unique morphs with different color variations and patterns.
Thus, iguanas can come with different colors such as yellow, grey, reddish, and turquoise. However, these colors become more prominent as they age.
Age is another factor that might contribute to the change of color in iguanas. For instance, iguanas tend to become darker as they age. Orange is mostly associated with breeding. Thus, if you see your iguana turning orange, you should know that the breeding season is at hand. Iguanas change their color to orange to lure the possible mates. They can retain the orange color long after the breeding season is over. The other reason why your iguana may turn to orange is when they want to dominate.
Thus, if you own other pets and house them together, they can turn their color to orange to show dominance. When baby iguanas are born, they usually have the very bright green. However, as they get older, their color starts to fade. Thus, they appear browner when they are older. Additionally, they also develop patterns such as zigzag, stripes, and other markings.
The approximate age that the iguanas start to turn brown is from the age one and half to two years. When Iguanas get cold, their color gets darker to attract more heat. To help your iguana destress, make sure to give it baths, mist it, hand feed it and even hold it if you think it is comfortable.
Some contact might help with de-stressing. This only in case if your iguana is established and tame. Your veterinarian may prescribe daily povidone-iodine soaks and an antibiotic ointment specifically for healing burned skin. In cases of severe burns, a lot of fluid can be lost, leading to severe dehydration.
Abscesses often appear as a swelling somewhere on the body. They are diagnosed by appearance, palpation, fine needle aspiration or surgical exploration. They are treated by surgical removal or lancing and flushing of the abscess. Many iguana owners bathe their lizards daily. Soaking is really good for iguanas in a few ways.
First and foremost, it moistens their skin, which can help prevent cracks, skin irritation, and infection. Your pet will also be breathing air that is higher in humidity while in the bathtub. Photoperiod: Iguanas generally need 14 hours of light and 10 hours of darkness.
The visible light and the UVB light source should be turned off at night to give the iguana a light-dark cycle. As mentioned above, supplemental heat may need to be added.
