Verified step by step guidance1
Identify the key characteristics of reptiles. Reptiles are a class of animals known for certain distinct features.
Understand that reptiles are ectothermic, meaning they are cold-blooded, not warm-blooded. This means they rely on external sources to regulate their body temperature.
Recognize that while some reptiles give birth to live young, many lay eggs. Therefore, giving birth to live young is not a universal characteristic of all reptiles.
Note that reptiles have scales covering their bodies. This is a defining characteristic of the class Reptilia, providing protection and helping to prevent water loss.
Understand that reptiles breathe air through lungs, not gills. Gills are characteristic of aquatic animals like fish.
