Turning black is a rather extreme color change, and most iguanas will not turn this dark normally.<\/p>\n\n\n\n<p><strong>Dark colors allow iguanas to take in more heat from the environment, and black is the darkest color they can turn. If your iguana turns black, it is likely quite cold, and you should check the temperature of its cage or turn up the heat in your house.<\/strong><\/p>\n\n\n\n<p>Iguanas may also turn black when extremely stressed, and they may tense up and become aggressive as well. Again, black is an extreme color change that is generally caused by extreme discomfort or stress.<\/p>\n\n\n\n<p><strong>A notable exception would be marine iguanas, which are naturally dark in color and may turn black after going for a swim simply because the water is cold. <\/strong>That said, marine iguanas are not generally kept as pets, so if your pet iguana is turning black, it is likely not for the same reason a marine iguana would turn black.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-is-my-iguana-turning-brown\">Why is My Iguana Turning Brown?<\/h2>\n\n\n\n<p>Many iguanas are naturally brown, or some shade of brown. If your brown iguana turns a different shade, this color change can give you clues about how it\u2019s responding to its environment.<\/p>\n\n\n\n<p><strong>For example, if you have a tan iguana, it may turn a darker brown when it\u2019s cold or an almost cream-colored white when it\u2019s hot. The darker color allows it to take in more heat, while the lighter color allows it to deflect more heat and light from the environment.<\/strong><\/p>\n\n\n\n<p>If your iguana isn\u2019t naturally a shade of brown, then turning brown may be a sign of illness; the iguana should be taken to the vet immediately.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-is-my-iguana-turning-green\">Why is My Iguana Turning Green?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1280\" height=\"853\" src=\"https:\/\/www.forestwildlife.org\/wp-content\/uploads\/2022\/02\/4-1.jpg\" alt=\"Why is My Iguana Turning Green?\" class=\"wp-image-10537\" srcset=\"https:\/\/www.forestwildlife.org\/wp-content\/uploads\/2022\/02\/4-1.jpg 1280w, https:\/\/www.forestwildlife.org\/wp-content\/uploads\/2022\/02\/4-1-300x200.jpg 300w, https:\/\/www.forestwildlife.org\/wp-content\/uploads\/2022\/02\/4-1-1024x682.jpg 1024w, https:\/\/www.forestwildlife.org\/wp-content\/uploads\/2022\/02\/4-1-768x512.jpg 768w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/><\/figure>\n\n\n\n<p>Most iguanas are born green with some brown markings; some species turn brown, red, or gray as they grow, and this is normal. Many iguanas remain a bright greenish blue into adulthood.<\/p>\n\n\n\n<p><strong>These greenish blue iguanas may turn more green in color when they are cold, stressed, or uncomfortable. They may also appear tense, with black skin visible between their scales, and their eyes will take on a darker red-brown color.&nbsp;<\/strong><\/p>\n\n\n\n<p>Iguanas may start out more blue and change from blue to green naturally as they grow. If this color change lasts and the iguana is showing no signs of stress or discomfort, then there\u2019s a good chance the young iguana has simply acquired a natural green color.<\/p>\n\n\n\n<p><strong>Iguanas that are naturally green may take on lighter or darker shades depending on temperature changes, much as other iguanas would. <\/strong>Cold temperatures will lead them to turn a darker shade of green; hot temperatures will turn their skin a lighter shade.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-is-my-iguana-turning-orange\">Why is My Iguana Turning Orange?<\/h2>\n\n\n\n<p><strong>Iguanas will turn an orange or rust color during the breeding season. They will typically change to this color long before breeding begins and maintain the color shading long after breeding ends.<\/strong><\/p>\n\n\n\n<p>Males will take on this orange or rust color over their entire body; they may not change color completely but will take on more rust-colored tones, as seen in the video above. Female iguanas don\u2019t change as much; typically they will only shift to the orange or rust color around the eyes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"do-iguanas-change-color-to-camouflage\">Do Iguanas Change Color to Camouflage?<\/h2>\n\n\n\n<p><strong>Not specifically. An iguana\u2019s color changing abilities may allow them to camouflage better, but they don\u2019t camouflage intentionally\u2013when they change colors, they have other reasons for doing so.<\/strong><\/p>\n\n\n\n<p>Iguanas are usually fairly well camouflaged to surroundings in the wild; for example, green and blue iguanas tend to live in brightly-colored rainforests, and <a href=\"https:\/\/oceana.org\/marine-life\/marine-iguana\/\" target=\"_blank\" rel=\"noreferrer noopener\">marine iguanas<\/a> live in the Galapagos Islands, where their muted gray colors allow them to blend in with the rocky shorelines where they spend most of their time.&nbsp;<\/p>\n\n\n\n<p>In short, most iguanas don\u2019t have any need to change color specifically to camouflage to their environment\u2013most are naturally similar in color to the trees, plants, and rocks around them.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"conclusion\">Conclusion<\/h2>\n\n\n\n<p>Iguanas have some natural color changing abilities. They may change color for many reasons, but the most common reason is that they will turn lighter or darker to help regulate their body temperature.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Have you ever seen an iguana turn from one color to a completely different color?
