To me, as long as you're drinking a bottle of water with it I see no harm. You get hydrated from coffee. Of course you need to drink water in general, but the concept of drinking cups of water to balance out dehydration from coffee is just a myth.
Reptiles do not maintain their own body temperature within a narrow range like mammals and birds, so controlling their environmental temperature is critical for normal activity and good health. Reptiles are poikilothermic-which means that their body temperature alters with the surrounding environmental temperature.
*They have a double life. * They have moist and scaleless skin. * Glands in skin that secrete mucus., which helps the skin keep moist. * Water and gases can pass through the amphibian skin easily, which allows the amphibians to breathe through their skin.
