Cold blooded does not mean reptiles have cold blood. They are, however, referred to as “cold-blooded” animals because of how they regulate their body temperatures through a process called thermoregulation.Know More
In thermoregulation, reptiles are able to regulate their own body temperatures by moving to different types of environments. If a reptile feels the need to warm up, it heads to an area where it senses warmer temperatures, such as a warm rock or an area with a warmer channel of air. It then stays in that place to readjust its internal body temperature. In turn, if the reptile requires cooling down, it seeks out a cooler location, such as a shady place or a body of water. Another way reptiles maintain body temperature is by huddling together with other reptiles to either warm up or cool down.
Reptiles differ from mammals because mammals must sweat to cool down or shiver their muscles to warm up. Sweating or shivering to regulate body temperature is referred to as endothermy. Mammals and even insects, such as bees, mimic traits of thermoregulation by seeking out warmth or cold. However, unlike reptiles, amphibians, insects, and other cold-blooded animals, mammals are not able to inherently regulate their body temperatures.Learn more about Reptiles
The main difference between reptiles and critters is the type of animal being referred to. Reptiles are cold-blooded animals such as snakes, turtles or lizards. The word "critters," on the other hand, is a slang term often used to refer to any type of animal, regardless of species. The term is sometimes used to refer to a person as well, usually in a derogatory manner.Full Answer >
All reptiles have scales or scutes that cover their skin, as this is a defining characteristic of the class Reptilia. Reptilian skin is horny and waterproof but lacks the thickness of mammalian skin. In some reptiles, the scales or scutes have a bony base that provides more protection.Full Answer >
Although most reptiles lay eggs, some reptiles retain the eggs, and the young are hatched inside the mother's body. Others are completely live-bearing, and no hatching is involved at all.Full Answer >
Reptiles live primarily in temperate and tropical climates. Reptiles are cold-blooded, which means they are unable to regulate the internal temperature of their bodies. Because of this, they have to live in warm and sunny climates.Full Answer >
