What key features characterize the Class Mammalia to which the West Highland White Terrier belongs?

Answer

They are warm-blooded (endothermic), possess hair or fur, and nurse their young with milk.

The Class Mammalia is defined by a suite of distinct biological characteristics that ensure the survival and development of their offspring. Key among these features are endothermy, allowing for stable internal body temperatures regardless of external conditions, the presence of hair or fur for insulation, and the unique ability of females to produce milk via specialized mammary glands to nourish their newborns following birth. These traits are fundamental to understanding the physiology of the Westie within the broader context of mammalian evolution.
