Reptiles That Change with Their Environment

Like all animals, reptiles are deeply affected by the ecosystem in which they live. Regardless of whether they live in the wild or as a pet, some reptiles are particularly environmentally sensitive, and vulnerable to even a small change around them. For these species, the effects of global warming will be especially devastating.

  1. Color Changing

    • Some species of reptiles can actually change skin color. Traditionally, it has been thought that color changing helps animals hide from predators, but other explanations exist as well. The most famous of the color-changing reptiles is the chameleon. According to Kidzworld, chameleons change as a reaction to light, temperature, mood and health. Anoles and iguanas also change color for many reasons, including stress and temperature. Occasionally, snakes change color, too; it's been discovered that the Kapuas mud snake changes color to camouflage itself.

    Temperature Regulation

    • Lizards are now facing extinction because their body temperatures are so closely linked with environmental temperature. Lizards bask in the sun to keep warm and to absorb vitamin D, and will move to the shade if they get too hot. Some reptiles, like chameleons, flatten and become darker to absorb more heat. These reptiles have an integral relationship with the environment. According to "The Independent," if climate change continues, up to 20 percent of the world's species of lizards could become extinct by 2080.

    Water Storage

    • Some reptiles adapt to water shortages. Reptiles that live in the desert will store water and nutrients in their bodies when they hibernate in the winter and estivate in the summer. According to the Arizona-Sonora Desert Museum, desert turtles have large bladders that can hold water, urea, uric acid and nitrogenous wastes during extended droughts. They can internally separate water from the urates, which they can expel as solids.

    Environmental Stress

    • Even a pet reptile can be susceptible to environment changes. Changes to its immediate enclosure, to its daily routine or to your home could result in behavioral or physiological changes. For example, it might develop shedding problems and changes in appetite, attitude or color.
