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
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 >
A list of 10 different reptiles might include: Loggerhead turtles, alligators, Komodo dragons, box turtles, black mambas, caimans, cobras, geckos, Monitor lizards and crocodiles. The study of reptiles is part of a branch of science called herpetology.Full Answer >
Modern biologists arrange the more than 8,000 living species of reptiles into four main groups: Squamata, Crocodilia, Testunides and Sphenodons. These groups are only distantly related, with some reptiles being more closely related to birds than to other reptiles, and so they do not represent a true clade, or evolutionary family. Instead, reptiles as a group are regarded as a "paraphyletic" family of animals.Full Answer >
Examples of the Reptilia, or reptiles, include common garter snakes, chameleons, saltwater crocodiles, tuataras and Galapagos tortoises. There are about 9,500 species in the Reptilia family, the earliest of which evolved about 315 million years ago.Full Answer >
