Yes, a wolf is indeed a mammal. Mammals are defined by certain characteristics, and wolves possess all of these key traits.
Firstly, like all mammals, wolves are warm-blooded, which means they can regulate their body temperature regardless of the environment. Secondly, wolves have fur, which is another typical feature of mammals; this fur provides insulation and helps them survive in various climates.
Moreover, wolves give live birth to their young instead of laying eggs, and they nurse their pups with milk produced by the mother. This ability to produce milk is a distinguishing characteristic of mammals.
Wolves belong to the Canidae family, which includes other species such as dogs and foxes. All these animals share common mammalian traits. Overall, the classification of wolves as mammals is based on these distinctive biological features.
